At time t = 0, an object attached to a coiled spring is at its resting position and moving down. Assuming that the motion is simple harmonic with period T, write an equation that relates the displacement d of the object from its rest position after t seconds. Also assume that the positive direction of the motion is up.a = 11;T = 3? seconds

A. d = -3 sin 
B. d = -11 cos 
C. d = -11 sin 
D. d = -11 sin
