Parachute V3

The applet shows the freebody diagram of the forces acting on a parachutist. The parachute is assumed to open fully instantaneously at t = 30 s 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.
