Q. A 1.25 kg ball begins rolling from rest with constant angular acceleration down a hill. If it takes 3.6s for it to make first complete revolution, how long will it take to make next complete revolution?

Q. On a frictionless table, a glob of clay of mass 0.340kg strikes a bar of mass 1.44kg perpendicularly at a point 0.10m from the center of the bar and sticks to it. If the bar is 0.70 m long and the clay is moving at 9.60m/s before striking the bar what angular speed does the bar/clay system rotate about its center of mass after the impact.
