A44 kg student on in-line skates is playing with a 22 kg exercise ball, disregarding friction, explain what happens in each situation: the student is holding the ball, and both are at rest. the student then throws the ball horizontally, causing the student to glide back at 3.5m/s. explain what happens to the ball in part (a) in terms of the momentum of the student and the momentum of the ball the student is initially at rest. the student then catches the ball, which is initially moving to the tight at 4.6 m/s. explain what happens in part (c) in terms of the momentum of the student and the momentum of the ball
