[-12 Points] DETAILS MY NOTES ASK YOUR TEACHER A ball of mass m = 1.75 kg is released from rest at a height h = 47.0 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 = 9.50 cm as in Figure [b] shown below. Neglecting any energy losses during the collision, find the following. T E, h 'LT its?
