A sky-diver falls vertically from a helicopter and reaches constant (terminal) velocity. The graph shows the variation with time t of the speed v of the sky-diver. [Graph] Which graph shows the variation with time t of the distance d fallen by the sky-diver?
AGraph of distance d vs time t, starting at 0, increasing with increasing gradient (accelerating).
BGraph of distance d vs time t, starting at 0, increasing with increasing gradient, then increasing with decreasing gradient.
CGraph of distance d vs time t, starting at 0, increasing with increasing gradient, then increasing linearly (constant velocity).
DGraph of distance d vs time t, starting at 0, increasing linearly, then with increasing gradient.
