11. A mass weighing 64 pounds stretches a spring 0.32 mass is initially released from a point 8 inches above the equilibrium position with a downward velocity of 5 ft/s. (a) Find the equation of motion. (b) What are the amplitude and period of motion? (c) How many complete cycles will the mass have completec at the end of 377 seconds? (d) At what time does the mass pass through the equilibrium position heading downward for the second time? (e) At what time does the mass attain its extreme displace ment on either side of the equilibrium position? (f) What is the position of the mass at t = 3 s? (g) What is the instantaneous velocity at 1 = 3 s? (h) What is the acceleration at t = 3 s? (i) What is the instantaneous velocity at the times when the mass passes through the equilibrium position? (j) At what times is the mass 5 inches below the equilibriun position? (k) At what times is the mass 5 inches below the equilibriur position heading in the upward direction?
