Question

@Abhisar
The diagram shows a square block at four positions along a track. The track is frictionless between points A and B, and rougher elsewhere.

Initially, the block is held in place against a spring by a horizontal external force. Then the external force is removed, and the block is projected forward. It travels down a ramp and across the rest of the track. It slides a distance S to a stop at point D.

To calculate the height h of the ramp, values for which set of variables are necessary? (Note: Vk refers to the speed of the block at a point shown in the diagram.)

Answer 1

Options
V2 and the mass of the block
V2 and the spring constant
V1, S, and the mass of the block
V1, S, and the coefficient of friction of the rough surface.

Answer 5

Its a spring against a block going velocity1 that falls height h and goes velocity 2
