A 10 kg block is released from point A in the figure. The track does not have friction except for the portion between points B and C, which has a length of 6.00 m. The block travels down the track, hits a spring with k = 2250 N/m of constant force and compresses the spring 0.3 m from its position of balance before reaching rest momentarily. Determine the coefficient of kinetic friction between the block and the surface between B and C.
