## Problem

The suspension system of a car contains springs that are compressed to absorb energy. One of the car’s springs (with a spring constant of 85, comma, 000, start text, N, slash, m, end text) is compressed 0, point, 019, start text, m, end text as the car moves up and down on a bumpy road.
Calculate the elastic potential energy of the compressed car spring.
