Question: A spring is used to stop a 200-lb package which is moving down a 20? incline. The spring has a constant k = 125 lb/in.

A spring is used to stop a 200-lb package which is moving down a 20? incline. The spring has a constant k = 125 lb/in. and is held by cables so that it is initially compressed 6 in. Knowing that the velocity of the package is 8 ft/s when it is 25 ft from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
