I know a few work-energy formulas. (Sorry if this is incorrect, but I study in French :blushing: ) :
Potential Energy and Ec (don't know the name in english)...
Ec1 + Ep1 = Ec2 + Ep2
1/2mv1^2 + mgh1 = 1/2mv2^2+mgh2
I know W = F*D or W=deltaEc= 1/2m(V2^2 - v1^2)
Is that the...
Make my day, please? :)
You and a bunch of your friends are trying to figure out what the force exerced on your bike's tires are by your brakes.
Here are the things that you have to help you figure out this problem:
-The road you're riding your bike down is completely horizontal
-You know...
Well, this is interesting. This question came up on my physics test, but I didn't know how to answer it. So I started browsing, and it was my friend that had actually found this exact link. (We were working together)
What I'm wondering is; How did you get 49x? We've been trying and trying...
