1. A 4.30 kg block is released from point A in the figure below. The track is frictionless 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 a spring constant of 2210 N/m ), and compresses the spring 19 cm from its equilibrium position before coming to rest momentarily. a. What is the potential energy of the system at point A ? (2) b. What is the potential energy stored in the spring when it is compressed by 19 cm ? (2) c. How much non-conservative work was done by the system? (2) d. Determine the coefficient of kinetic friction, μk, between the block and the rough surface. (3) e. What happened to the lost mechanical energy? (1)
