An object of mass m (in grams) attached to a coiled spring with damping factor b (in grams per second) is pulled down a distance a (in centimeters) from its rest position and then released. Assume that the positive direction of the motion is up and the period is T (in seconds) under simple harmonic motion. Develop a model that relates the distance d of the object from its rest position after t seconds.m =20, a = 13, b = 0.9, T = 6
A. d = 13e-0.9t/40 cos 
B. d = -13e-0.9t/40 cos 
C. d = -13e-0.9t/40 cos 
D. d = 13e0.9t/40 cos
