A 1.80kg , horizontal, uniform tray is attached to a vertical ideal spring of force constant 195N/m and a 290g 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 16.1cm 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? (Hint: This does not occur when the ball and tray reach their maximum speeds.)
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?
