The "spring-flex" exercise system consists of a spring with one end fixed and a handle on the other end. the idea is that you exercise your muscles by stretching the spring from its natural length, which is 37 cm. if a 160 newton force is required to keep the spring stretched to a length of 47 cm, how much work is required to stretch it from 56 cm to 69 cm?
