+1 862 207 3288 equilibrium position
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 t = p/12, p/8, p/6, p/4, and 9p/32 s.
(b) What is the velocity of the mass when t = 3p/16 s? In which direction is the mass heading at this instant?
(c) At what times does the mass pass through the equilibrium position?
