A sky diver falls vertically from a stationary balloon. She leaves the balloon at time t = 0. At time t = T, she reaches terminal velocity. Beyond the time shown in the graphs, she opens her parachute. Which graph shows the variation with time t of the force F due to air resistance?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AGraph with F increasing linearly from 0, then constant.
BGraph with F increasing with an upward curve from 0, then constant after t=T.
CGraph with F increasing linearly from 0.
DGraph with F decreasing from a maximum value.
✓ Correct answer
B: Graph with F increasing with an upward curve from 0, then constant after t=T.
