A block with mass m = 2.00 kg is placed against a spring on a frictionless incline with angle ? = 34°. (The block is not attached to the spring). The spring, with spring constant k = 19.8 N/cm, is compressed 15.7 cm and then released. What is the elastic potential energy of the compressed spring? What is the change in the gravitational potential energy of the block-Earth system as the block moves from the release point to its highest point on the incline? How far along the incline is the highest point from the release point?
