A firefighter who weighs 192 lb slides down an infinitely long fire pole that exerts a frictional resistive force with magnitude proportional to her speed with constant of proportionality k. Find her velocity v as a function of t, given that her terminal velocity is -16 ft/s. Assume that she starts from rest. Solve for the solution of this Application of first order differential equation in Dynamics. the final answer is v= -16 (1-e-2t)
