1. The problem statement, all variables and given/known data A hollow, 50N ball and a 50N hoop are released from rest at the top of a 3m long ramp. Both objects have a diameter of .5m. If the ball reaches the bottom in 5s, and the hoop in 7s, find (for each object): a. velocity at the bottom b. angular speed at bottom c. moment of intertia at bottom d. rotational kinetic energy at bottom e. angular momentum at bottom 2. Relevant equations d=1/2at^2+Vot I=mr^2 That's another part of the problem: I don't know the needed equations 3. The attempt at a solution I answered part A correctly, using d=1/2at^2, but the rest I bombed. I attempted using 2πr/t for part B, I=mr^2 for C, KE=1/2mv^2 for D, and mvr for E, all of which were wrong. Any help would be appreciated.
