The drag force on large objects such as
cars, planes, and sky divers moving through air is more nearly FD = bv2 (a)
For this quadratic dependence on v, determine a formula for the terminal
velocity VT, of a vertically falling object, (b) A 75-kg sky diver
has a terminal velocity of about 60 m/s; determine the value of the constant b.
(c) Sketch a curve like that of Fig. 5-27b for this case of . For the same terminal velocity, would this curve lie above or below
that in Fig. 5 27? Explain why.
