A) A 5.0-kg block is released from rest at point A. The track is frictionless except for the portion between points B and C, which has a length of 8.0 m. The block travels down the track, hits a spring of force, constant 2000 N / m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. Determine the coefficient of kinetic friction between the block and the rough surface between points B and C.assume...
