The applet shows the freebody diagram of the forces acting on a parachutist.[br]The parachute takes sometime to open fully as shown in the purple section of the v-t graph.[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 so as to avoid [br]confusion since the scale is different from the v-t graph.
