An elevator of mass M is at rest when its cable breaks. The elevator falls a distance h before it encounters a massless, cushioning spring (with spring constant k) at the bottom of the shaft. The spring has an uncompressed height of L. As the elevator falls, its safety clamp applies a frictional force of f on the elevator to help slow it down (this frictional force is much less than the force of gravity on the elevator)
1. Write an expression for the speed of the elevator before it encounters the spring.

Aspring 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.)
