A 7.0 kg box is attached to a spring that is compressed a distance of 0.5 meters. When the box is released from the spring, it moves to the right towards a 3 m tall hill. The spring constant is 550 N/m. Assume that there is no friction in the system. a. How much potential energy is stored in the spring while it is compressed? b. What is the kinetic energy (energía cinética) of the box right after being released from the spring?
