A spring is such that it would be stretched 6 in. by a 12-lb weight. Let the weight be attached to a spring and pulled down 4 in. below the equilibrium point. If the weight is started with an upward velocity of 2 ft/sec, find the expression for the position of the ball at any time t. Note that at t=0, the position of the ball is xo = =ft (or 4 in. below equilibrium point).
