A block with mass m = 1.86 kg is placed against a spring on a frictionless incline with angle θ = 33.9° (see the figure). (The block is not attached to the spring.) The spring, with spring constant k = 25 N/cm, is compressed 28.1 cm and then released. (a) What is the elastic potential energy of the compressed spring? (b) 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? (c) How far along the incline is the highest point from the release point?

A wooden block with mass 1.95 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 35.0degree (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.00 m up the incline from A, the block is moving up the incline at a speed of 6.15 m/s and is no longer in contact with the spring. The coefficient of kinetic between the...
