36. 



The diagram shows a 0.74-kg square block at four positions along a track. The track is frictionless between points A and B. Elsewhere, the coefficient of static friction on the block is 0.36.

Initially, the block is held in place against a spring by a horizontal external force of magnitude 29 N. Then the external force is removed, and the block is projected forward with speed . The block descends a ramp and has speed  at the bottom. At point C, its speed is . The block stops at point D.

 

What is the height h of the ramp?
