A mass weighing 4 pounds is attached to a spring with a spring constant of 2 lb/ft. The mass is initially released from a point 1 foot above the equilibrium position with a downward velocity of 8 ft/s. Assume that the medium offers a damping force that is numerically equal to the instantaneous velocity.
