the rules of tennis specify that the 0.057-kg ball must bounce to a height of between 53 and 58 inches when dropped from a height of 100 inches onto a concrete slab. what is the change in the momentum of the ball during the collision with the concrete? you will have to use some free-fall kinematics to answer this question. ignore air resistance.
