Can I get some help on this?

Hooke's Law for Springs. According to Hooke's law, the force required to compress or stretch a spring from an equilibrium position is given by F(x)=kx, for some constant k. The value of k (measured in force units per unit length) depends on the physical characteristics of the spring. The constant k is called the spring constant and is always positive. Part 1. Suppose that it takes a force of 11N to compress a spring 1.6m from the equilibrium position. Find the force function, F(x), for the spring described. F(x)= Part 2. Setup the integral that will give the work required to stretch the spring 1m from the equilibrium position. W= Part 3. Calculate the work done by the force described above. W=J
