Parachute V4
The applet shows the freebody diagram of the forces acting on a parachutist.
The parachute takes sometime to open fully as shown in the purple section of the v-t graph.
Two options are available;
1. The freebody diagram moves along the v-t graph.
2. The freebody diagram moves along the d-t graph which is however not drawn so as to avoid
confusion since the scale is different from the v-t graph.
