The spring constant k is measured in N/m because it is essentially "how many Newtons required to
stretch a spring one meter", therefore, the relationship between force, spring constant, and
distance stretched (or compressed) is F = kx. With this in mind, an archer pulls a bowstring back 0.4 m by exerting a force that increases uniformly from 0 to 230 N. What is the spring constant of the bow?
