9702Non-uniform motion

A skydiver leaves a stationary balloon and falls vertically through a long distance. Which graph best represents the variation of the acceleration a of the skydiver with the distance s travelled as she falls through the air?

  1. AGraph of a against s: a decreases from a maximum at s = 0 towards zero as s increases
  2. BGraph of a against s: a increases from zero at s = 0, curving towards a constant value
  3. CGraph of a against s: a is constant (horizontal line) for all s
  4. DGraph of a against s: a increases linearly from zero at s = 0
