[15] The pictures from Vischer's Ferry were better though, as despite the name I didn't see much…, Entry: Science is Cool: Know Your Science Who says that I used the correct origin? Here is a picture. Former Mythbusters host and professional racing driver Jessi Combs has died following a car accident in Oregon’s Alvord Desert. Combs, 36, was known as the fastest woman on four wheels after setting the women’s … Hey guys, I just discovered this forum and have a question for yall. This particular record was set by Lee Breedlove in 1965, with an official run of 308.51 mph. Oh yeah, and they invited me to join. How would I explain this? I already mentioned the MythBusters' crashing two cars episode where they correctly doubled the speed of a pendulum type object. Celena- Carl Wunsche Sr High School Career Academy in Spring,TX They want to show that if you shoot a ball at -60 mph with respect to the truck (that would be v') and the truck is moving at 60 mph (that would be s) then v = 0 mph. This is ultracentrifuge angular velocity. There will be one coordinate system (x) and another one (x') that is moving away from x with a speed s. The ball in question is only moving in the x (and x') direction. Jessi Combs, Race Car Driver and ‘Mythbusters’ Host, Dies at 36 Trying to Break Her Own Speed Record Known as the “fastest woman on four wheels,” Combs set a record of 398 mph in 2013 The whole thing is pretty heavy. Not only did she answer the "What the heck is this?" Here is the definition for velocity: I complained about MythBuster's explanation of relative velocity, It doesn't matter that the two frames are not at the same place at t = 0. Physics Related Episodes of Mythbusters SEASON 1 ! Adam built an acrylic wind tunnel (much like the one in the Penny Drop myth). The Myth - A penny dropped from a skyscraper lands with enough force to either kill a pedestrian on the sidewalk below or embed itself into the sidewalk. Ok - now for the x-velocity in the first frame after this time t: I know an expression for x2 also, since the two frames where at the same place at t = 0, x1 and x'1 have the same value. Chris Malik Chambers(15) and Celena DeShay Chambers (16) The following overview attempts to summarize and categorize the results of the entire MythBusters series as succinctly as possible. If the acceleration is zero, I could drop this. But wait. Chris- DeKaney High School in Houston, TX The origin is not a real thing, so I can change it if I like. If you would like a homework assignment, you can show: ScienceBlogs is where scientists communicate directly with the public. And so the velocity tells how this vector r changes. Basically, he wanted to collide something into a wall at one speed and then double that speed. Tracy: Ok. Privacy statement. She brought about Velocity channel's All Girls Garage, and was a host and builder on a season of Discovery Channel's Mythbusters. Celena- Math . (they also say this is a professional driver on a closed course and don't try this…, I complained about MythBuster's explanation of relative velocity, More projectile motion than you can shake a stick at, The First 3D Printed House Is On The Market, And It Still Costs $300,000, How Fast Can Dogs Learn New Words? The absolute, only difference between velocity and speed is that velocity also describes direction, whereas speed doesn't. I keep having to make a choice. So, I did. … Tracy: Dig. What if there are two origins? No, they won’t… VF=VI+AT, where Velocity Final is the end speed, Velocity Initial is the start speed (probably anywhere from 400 to 1000 feet per second depending what ammo you are using) and AT is the Accelleration x Time factor (32 feet per second-per second over the time the bullet travels to ground.) Also, 2X the speed means 4X the energy, so you’d need to raise the pistons to 4X the height to get to the same energy as double the speed. The absolute, only difference between velocity and speed is that velocity also describes direction, whereas speed doesn't. Verdict - Busted Notes - Firing a penny at terminal velocity (65 miles per hour (105 km/h)) into concrete and asphalt disks and a ballistics gel head with a human skull failed to result in any penetrations, likely because the speed is too … You can also shop using Amazon Smile and though you pay nothing more we get a tiny something. This brings a couple of important notes. MythBusters For High School Physics ... Model the person as an upright rectangular box moving through the rain at speed V as shown. The breakthroughs and innovations that we uncover lead to new ways of thinking, new connections, and new industries. Air was shot up through the bottom and a bullet was dropped into the chamber. The speed of the ball with respect to the car is 60 mph to the right (negative) and the speed of the car with respect to the ground is 60 mph to the left (positive). All rights reserved. This quantity must be determined Air was shot up through the bottom and a bullet was dropped into the chamber. And the clay/car-mush-length-percentage-reduction measurement seems odd … Overall, this … What are your favorite subjects and school activities? Here is the deal. +1 to your comment though. Mythbusters Bullet velocity Thread starter jones106; Start date Jan 20, 2007; Jan 20, 2007 #1 jones106. It is the essential source of information and ideas that make sense of a world in constant transformation. In their full-scale tests, the MythBusters crashed two cars into a wall at 50 and 100 mph as references. I would start by saying that velocity is relative. It is of course a gas discharge tube. So, I complained about MythBuster's explanation of relative velocity. Doubling the height would get you to 1.414142 times the speed, or only 70.7107 mph. But you would think there must be a comprehensive resource out there which covers the physics of Mythbusters … However, if a bullet is fired upward at a non-vertical angle (a far more probable possibility), it will maintain its spin and will reach a high enough speed … Watermelon…, Actually, it should be called Happy "Magnitude of the local Earth gravitational field" day. If the frame on the right is moving with a speed s with respect to the other frame then: This form is only true if the two frames are at the same location at t = 0 - but in the end, the result will be the same no matter where the two frames are at t = 0. Terminal velocity of a falling bullet. Well, the idea was for the physics students and faculty to build some stuff to do outside - projectile motion type stuff. Former 'Mythbusters' host dies in jet car crash attempting speed record Aug. 28, 2019 01:05 Aug. 28, 2019, 6:51 PM UTC / Updated Aug. 29, 2019, 12:58 AM UTC What if there are two origins? Are radar guns inaccurate, or unable to pick up the velocity of objects of high speed and small size? The origin is not a real thing, so I can change it if I like. Here is a picture at some time later (I call it t). But wait. This looks bad, but she seems to not be seriously injured. Chris and Celena Chambers Adam built an acrylic wind tunnel (much like the one in the Penny Drop myth). The Myth - A penny dropped from a skyscraper lands with enough force to either kill a pedestrian on the sidewalk below or embed itself into the sidewalk. Couldn't I use a different one? To revist this article, visit My Profile, then View saved stories. Back to the Mythbusters The MythBusters test if bullets fired up ... and fall at a much slower speed due to terminal velocity and is therefore rendered less than lethal on impact. Professional speed racer and former host of the popular TV show 'Mythbusters', Jessi Combs died Tuesday at the age of 39 in a crash in the Alvord Desert in Oregon as she was piloting a jet car attempting to again break the land-speed record, NBC News reported, citing local authorities. Here is the next item. Kenneth: A menorah. 2013 – Set women's land speed record – 398 mph with a top speed of 440 mph 2011 – SCORE Baja 1000 – 2nd – Class 10 [14] On October 9, 2013, Combs drove the North American Eagle (NaE) Supersonic Speed Challenger at the Alvord desert, claiming the women's 4-wheel land speed record with an official run of 398.954 mph (632 km/h) and a top speed of 440.709 mph (709 km/h). Kenneth: A picture of President Obama for the Muslims. ... House of Popcorn High Speed. The MythBusters tested over 1,000 distinct myths in 271 hour-long episodes spanning 14 years, resulting in a vast amount of information about common myths and interesting phenomena. Well, we had the idea a while…, Congratulations Fran. Their results showed that two objects hitting each other at 1x speed will cause 1x damage. So, I complained about MythBuster's explanation of relative velocity. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of Condé Nast. I will get there. This is one of my…, I don't really know what that title actually means. It also became obvious that the physics explanations given on the show don't go very deep.
