Tutorial: Using energy bar charts for conservation of energy problems G. A 10.0-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 of force constant 2 250 N/m, and compresses the spring 0.300 m from its equilibrium position before coming to rest momentarily. Determine the coefficient of kinetic friction between the block and the rough surface between B and C. Hint1: You should draw a FBD on the block when it is on the portion between B and C. Hint2: You do NOT need to figure out the speed at point B or at point C in order to answer the question. You can, but it's a waste of time. 3.00 m 6.00 m B C
