A ball of mass m = 1.95 kg is released from rest at a height h = 72.0 cm above a light vertical spring of force constant k as in Figure [a] shown below. The ball strikes the top of the
spring and compresses it a distance d = 8.30 cm as in Figure [b] shown below. Neglecting any energy losses during the collision, find the following.
