A 3.2 kg block is released from rest at point A. The track is frictionless except for the rough portion between points B and C. 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. What is the work done by the friction force as the block moves from B to C? 3.00 m B O Use g = 10 m/s
