8 A mass weighing 16 pounds stretches a spring feet The mass is initially released from rest from a point 3 feet below the equilibrium position and the subsequent motion takes place in a medium that offers a 3 1 the instantaneous velocity Find the equation of motion x t if the mass is driven by an external force equal to f t 10 cos 3t Use g 32 ft s2 for the acceleration damping force that is numerically equal to 2 due to gravity x t ft
