(a) A father of mass 65 kg is standing still on a frictionless ice-covered pond when he tosses a 1 kg football to his son with a velocity of 18 m/s. Determine the father's velocity after throwing it. (b)The son of mass 28 kg is standing still on the same frictionless ice-covered pond when he catches the football. Determine the child's velocity after catching it. What's the coefficient of restitution for this case?
