A 16-lb weight is attached to a 5 ft long spring. At equilibrium the spring measures 8.2 feet. If the weight is pushed up and released from rest at a point 2 feet above the equilibrium position, find the displacements x(t)if it is further known that the surrounding medium offers a resistance numerically equal to the instantaneous velocity
