a) A 15.0 kg block is released from rest at 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 of force constant 2,300 N/m, and compresses the spring 0.250 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. 3.00 m A Need Help? B -369.125 X Think carefully about what terms correspond to the initial mechanical energy and the final mechanical energy and how they are related to the change in internal energy of the system due to the friction force. m 6.00 m- b) What If? The spring now expands, forcing the block back to the left. Does the block reach point B? Yes No C If the block does reach point B, how far up the curved portion of the track does it reach, and if it does not, how far short of point B does the block come to a stop? (Enter your answer in m.) Master It
