A 0.30-kg mass is suspended on a spring. In equilibrium the mass stretches the spring 2.0 cm downward. The mass is then pulled an additional distance of 1.0 cm down and released from rest. Write down its equation of motion.
 
  A) y = (0.01 m) cos (22.1 t)
  B) y = (0.01 m) sin (22.1 t)
  C) y = (0.03 m) cos (22.1 t)
  D) y = (0.03 m) sin (22.1 t)
