Question

A 10 kg block is released from point A in the figure. The track is frictionless, except for the portion between points B and C that is 7.6 m long. The block goes down the saw, hits a force constant 2250N / m spring, and compresses the spring 0.30 cm from its equilibrium position, before momentarily stopping. If the coefficient of kinetic friction between the block and the rough surface between B and C is 0.32. Determine the height from where the block is released.
