@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.)
