A small block is at the top of a frictionless track. The track slopes down, runs horizontally and then ends in a spring attached to a stop. The block is released, slides down the track and compresses the spring. How much is the spring compressed before it springs back and reverses the direction of the block? (Block mass = .035 kg, track height = 0.78 m, k= 380 N/m).
