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 = 30, a = 10, b = 0.55, T = 6

A. d = -10e-0.55t/60 cos 
B. d = -10e-0.55t/60 cos 
C. d = 10e0.55t/60 cos 
D. d = 10e-0.55t/60 cos
