## Physics for Scientists and Engineers: A Strategic Approach with Modern Physics (4th Edition)

We can find the force that the spring pushes when it is compressed 5.0 cm: $F = kx$ $F = (750~N/m)(0.050~m)$ $F = 37.5~N$ The spring pushes with a force of 37.5 N. According to Newton's third law, the athlete must also be pushing with a force of 37.5 N.
