A mass weighing 20 pounds stretches a spring 6 inches. The mass is initially released from rest from a point 6 inches below the equilibrium position. (a) Find the position of the mass at the times 1 = 7/12, T/8, 7/6, 7/4, and 97/32 s. (b) What is the velocity of the mass when 1 = 37/16 s? In which direction is the mass heading at this instant?
