A 10.0 kg black is released from point A. The track is frictionless except for the portion among points B and C, which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2250N/m, and compresses the spring 0.300 m from its equilibrium position before coming to rest momentarily. Decide the coefficient of kinetic friction between the block and the rough surface among B and C.
