A 1.00 kg , horizontal, uniform tray is attached to a vertical ideal spring of force constant 195 N/m and a 285 g metal ball is in the tray. The spring is below the tray, so it can oscillate up-and-down. The tray is then pushed down 12.1 cm below its equilibrium point (call this point A) and released from rest.
a) How high above point A will the tray be when the metal ball leaves the tray?
b) How much time elapses between releasing the system at point A and the ball leaving the tray?
c) How fast is the ball moving just as it leaves the tray?
