When a chip jumps, the energy comes from the muscles, but also from an elastic protein which is subjected to a compression similar to that of a spring. If a chip, with a mass of 2.0 × 10-7 kg, jumps vertically from a height of 65 mm, and 75% of the energy comes from the elastic protein, determine the initial amount of this energy.
