A 1.75 block slides with a speed of 0.925 on a frictionless horizontal surface until it encounters a spring with a force constant of 869 . The block comes to rest after compressing the spring 4.15. Find the spring potential energy, the kinetic energy of the block, and the total mechanical energy of the system, for compressions of 0. Find the spring potential energy, the kinetic energy of the block, and the total mechanical energy of the system, for compressions of 1.00.
