Asked by Andreea
A block with mass m = 2.00 kg is placed against a spring on a frictionless incline with angle θ=30.0° (see figure). The block is NOT attached to the spring. The spring, with spring constant k = 19.6 N/cm, is compressed 20.0 cm from its unloaded equilibrium length and then released.
(a) What is the elastic potential energy of the compressed spring?
(b) What is the change in gravitational potential energy of the block+Earth system as the block moves from the release point to its highest point on the incline?
