Shown in the figure below is a set of two masses on a track. There is no friction in this problem. The small mass, m = 1.63 kg, is initially stationary at a height of y₁ = 1.49 meters. The large mass, M = 4.51 kg, is stationary on the flat surface.

\fo 1 > 2 : The small mass slides down the ramp. 0 2 =- 3 : The small and large mass collide elastically. o 3 > 4 : The small and large mass recede from each other after the elastic collision
