How to solve loop the loop with rotational kinematics?
I didn't check the v=5.512, using it, I got the same answer. I agree with the expression, which I simplified to mg(h-2R) = 1/2mv^2 +1/2(2/5)MR^2(w^2) gh = 1/2v^2 +(2/10)(v^2) h-2R=7/(10*g)v^2 =2.17 m For a disk, the moment of inertia become... Read More »

How would you do this problem if instead a ball rolled 37.0 meters in 3 seconds, and at the end of the 3 seconds it was moving at 98 m/s? Take those equations replace, x with theta, v with omega, a with alpha and you have the proper equatio... Read More »
