. Sky Diving A sky diver jumps from a reasonable height above the ground. The air resistance she experiences is pro- portional to her velocity, and the constant of proportionality is 0.2. It can be shown that the downward velocity of the sky diver at time t is given by v(t) = 180(1 – e-0) where t is measured in seconds (s) and v(1) is measured in feet per second (ft/s). (a) Find the initial velocity of the sky diver. (b) Find the velocity after 5 s and after 10 s. (c) Draw a graph of the velocity function v(t). (d) The maximum velocity of a falling object with wind resistance is called its terminal velocity. From the graph in part (c) find the terminal velocity of this sky diver. v(t) = 180(1 - e1)
