A sky-diver falls from a stationary balloon at time t = 0. As the sky-diver falls, her speed and the air resistance increase until the force of the air resistance is equal to her weight. Which graph best shows the variation with time t of the displacement s for the motion of the sky-diver?

1. AGraph A: s-t curve starting at origin, increasing with increasing gradient
2. BGraph B: s-t curve starting at origin, increasing with decreasing gradient
3. CGraph C: s-t curve starting at origin, increasing with decreasing gradient, approaching a constant value
4. DGraph D: s-t straight line through origin
