A skydiver of mass 75 kg jumps from an aircraft.
The graph in Fig. 1.1 shows the vertical velocity of the skydiver during the first 40 s of the fall before opening his parachute.

Explain the shape of the graph
Fig. 1.2 shows the skydiver falling at a constant velocity.
Add labelled arrows to Fig. 1.2 to show the forces acting on the skydiver.
Fig. 1.2
The skydiver opens his parachute after 40 s.
On Fig. 1.3 below, complete the graph to show how the skydiver’s vertical velocity changes after 40 s.
