Video transcript

what I want to do in this video is show you a very cool video and then pose a question but I want to make sure that the video everything is up and up on the in terms of the copyright laws so the video I'm going to show you is from a show called the fifth gear that appears on channel 5 I believe in the United Kingdom and I think I'm okay on good copyright grounds to claim fair use here because obviously the point of this I'm going to ask a math question about the video that we're going to see and so fair use laws the purpose and character of use including whether such as a commercial nature or non-profit educational purposes we are definitely the latter non-profit educational purposes we are actually that we aren't trying to in any way replace the work being used I'm just going to show a little snippet of it so we can use it as the basis for a problem and then this is kind of the meat of fair use law reviewer may fairly cite largely from the original work if his design if his design be really and truly to use the passages for the purpose of fair and reasonable criticism in this case it's fair and reasonable math problem or physics problem on the other hand it is as clear that if he does cites the most important parts of the work with the view not to criticize but to see per supersede the use of the original work and substitute the review for it such will such a use will be deemed in law of piracy so in no way do I want to supersede it you should go look it up you should watch the show this is not good enough I'm just I don't even have the sound on and it's going to be a little small little window here where I'm just going to show this really really the part where they actually do a loop-de-loop now with that other way this is where you can find more information about fifth gear which is on channel 5 now let me actually show you the video I'm going to have the sound down and so this is the video right over here it's a pretty neat video this guy is going to attempt to do a loop-de-loop and he's actually going to succeed at doing the loopty-loop and what I want you to do and the question I want you to pose is look at this video and get a stopwatch and get or get it whatever else you need out a ruler or whatever else you might need to do and try to figure out what we're going to do two things we're going to figure out what the minimum velocity that the car needs to complete the blue and we're also going to try to figure out what his actual velocity was over the course of the loop-de-loop so let's actually just watch this video so there he goes he's starting he's accelerating toward looks like he's just crossed almost he's pushing almost 40 miles an hour at least I'm assuming that was miles per hour this is a British show and then he hits he hits the loop-de-loop and then he finishes it and he's done so let's think about for the next video let's think about if we can figure out what the minimum what the minimum velocity or I should say the magnitude of his velocity or speed had to be to actually complete the loop right over here and then we can actually get a stopwatch later on to figure out what his average velocity actually was
