Question

A firefighter who weighs 118 lb slides down an infinitely long fire pole that exerts a frictional resistive force with magnitude proportional to her speed, with k=2.9 lb-s/ft. Assuming that she starts from rest, find her velocity as a function of time and find her terminal velocity. v(t) = Terminal Velocity =
