2. In physics, the work done by a force is calculated as W = I: F (x) dx. The force needed to compress or stretch a spring is given by the equation F F (x) = kx, where k is the spring constant. Calculate m _' the work done when you stretch a spring 6 cm from o 1 2 3 4 5 5 its rest length, when the spring constant k = 12 N/cm. How much work do you do going from 3 cm to W 6cm?(10p) """
