You place the left end of the rod on a fulcrum, and hang the right end from a spring
of spring constant 800 N/m. The spring is stretched 0.3 m from its equilibrium
length and the rod is horizontally level and at rest.
How much force Fspr is the spring applying to the right end of the rod?

A spring with a mass of 2 kg has a damping constant 14 kg/s. A force of 3.6 N is required to keep the spring stretched 0.3 m beyond its natural length. The spring is stretched 0.6 m beyond its natural length and then released. Find the position of the mass at any time t. (Assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)
