**20. A 4-kg block is attached to a spring, and oscillates horizontally on a frictionless table- top. The spring has constant k = 1875 N/m. The maximum speed measured for the block is v=10 m/s a) What is the total mechanical energy of the block-spring system? Explain b) When the block is moving at a speed ofv 5 m/s, how far is the spring stretched (or compressed)?
