A box is at rest on a sloped hill. The 50-g box is pushed into a spring with a spring constant of 51 N/m compressing the spring by 4.3 cm. a. Assuming no energy is lost what is the height gain of the box when the spring is released? b. If the slope is at a 23-degree angle, how far along the hill will the box travel? If the box only slides 8 cm along the slope, what percent of the orginal energy was disapated due to friction and other external forces?
