Answer 2

A 10-kg block is released from rest at point A in the figure. The track is frictionless except for the portion between points B and C, which has a length of 6 meters. The block travels down the track, hits a spring of force constant 2250 N/m, and compresses the spring 0.3 meters from its equilibrium position before combing to rest momentarily. Determine the coefficient of kinetic friction between the heavy block and the rough surface between points B and C.
