graphing calculator is recommended. sky diver jumps from a reasonable height above the ground. The air resistance she experiences is proportional to her velocity, and the constant of proportionality 0.17. It can be shown that the downward velocity of the sky diver at time t is given by v(t) = 150(1e-0.17t) here t is measured in seconds (s) and v(t) is measured in feet per second (ft/s). (a) Find the initial velocity of the sky diver. ft/s (b) Find the velocity after 3 s and after 13 s. (Round your answers to one decimal place.) after 3 s ft/s ft/s after 13 s (c) Draw a graph of the velocity function v(t).
