A spring is such that a 4-lb weight stretches the spring 0.40 ft. The 4-lb weight attached to the spring (suspended from a fixed support) and the system is allowed t reach equilibrium. Then the weight is started from equilibrium position with a imparted upward velocity of 2 ft/sec. Assume that the motion takes place in a mediur that furnishes a retarding force of magnitude numerically equal to the speed, in fe per second, of the moving weight. Determine the position of the weight as a functio of time.
