11. a. A mass weighing 64 pounds stretches a spring 5.12 feet. Assuming a damping force that is 10 times the velocity of the mass, determine the equation of the motion, if the mass is initially released from a point 1 foot below the equilibrium position with a upward velocity of 5 ft/s. b. Determine when the object passes through the equilibrium position (f at al) c. Determine when the object reaches a maximum displacement above the equilibrium position. (for the solution look at lecture notes)
