Find the elastic potential energy of the compressed spring

Reference no: EM13332798

A block with mass m = 3.58 kg is placed against a spring on a frictionless incline with angle ? = 32.5° (see the figure). (The block is not attached to the spring.) The spring, with spring constant k = 18 N/cm, is compressed 12.2 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?
