Aforce of 9 pounds stretches a spring 1 foot. a mass weighing 6.4 pounds is attached to the spring, and the system is then immersed in a medium that offers a damping force numerically equal to 1.2 times the instantaneous velocity. (a) find the equation of motion if the mass is initially released from rest from a point 1 foot above the equilibrium position.
