A1.60 kg , horizontal, uniform tray is attached to a vertical ideal spring of force constant 195 n/m and a 290 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 15.1 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? (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?
