The applet shows the freebody diagram of the forces acting on a parachutist.[br]The parachute is assumed to open fully instantaneously at t = 30 s[br]Two options are available;[br]1. The freebody diagram moves along the v-t graph.[br]2. The freebody diagram moves along the d-t graph which is however not drawn [br]so as to avoid confusion since the scale is different from the v-t graph.
