Question
(a) A 15.0 kg block is released from rest at point A 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.
