A spring with a 4 kg mass is resting on a horizontal frictionless table and is attached to a wall at the left end. It will stretch 0.5 m beyond its natural length when a force of 12 N is applied. If the spring begins at the equilibrium position and is pushed to the right with an initial velocity of 3 m/s, find the position of the mass after t seconds. (Assume that movement to the right is the positive x direction.)
