A 2.00 kg block is placed against a spring on a frictionless30.0 degree incline. The spring, whose spring constant is19.6N/cm is compressed 20.0 cm and then released.
a.) What is the elastic potential energy of the compressedspring?
b.) What is the change in the gravitational potential energyof the block-Earth system as the block moves from the release pointto its highest point on the incline?
c.) How far along the incline is the highest point from therelease point?
