A 3.0-kg block sliding on a frictionless horizontal surface is accelerated by a compressed spring. If the 200 N/m spring is initially compressed 10 cm, determine (a) the potential energy stored in the spring. As the block leaves the spring, find (b) the kinetic energy of the block, and (c) the velocity of the block.
