53. Since the valley is frictionless, the only reason for the speed being less when it reaches the higher level is the gain in potential energy ΔU= mghwhere h= 1.1 m. Sliding along the rough surface of the higher level, the block finally stops since its remaining kinetic energy has turned to thermal energy
