Describe the direction of the force that makes the ball acquire the maximum tangential velocity for the force applied. Change the angle and the mass of the ball to determine the answers to the following questions. You may change the mass of the object dropped on the merry-go-round and assume that the merry-go-round is a solid, uniform disk.
