A mass of 1.0 kg is pushed against a spring with a spring constant of 25 N/m. As a result, the spring is compressed by 20 cm. The mass is then released.
(a) What is the amount of potential energy acquired by the spring when it is compressed?
(b) What is the kinetic energy of the mass after the mass is released and it is no longer in contact with the spring?
