A body of mass 5.0 kg is suspended by a spring which stretches 10 cm when the mass is attached. It is then displaced downward an additional 5.0 cm and released. Its position as a function of time is approximately
 a. y = -0.10 sin 9.9t
  b. y = 0.10 cos 9.9t
  c. y = -0.10 cos (9.9t + .1)
  d. y = 0.10 sin (9.9t + 5)
  e. y = -0.05 cos 9.9t
