An object attached to a coiled spring is pulled down a distance a from its rest position and then released. 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 = 13;
T = 7 seconds
A. d = -13 sin 
B. d = -13 cos 
C. d = -7 cos
