How do I solve for this question?

scanning once you write down in hatbox. 1. The pulley system shown is at rest when the motor M starts pulling in rope to lift the 120 lb cargo C. For the first second of operation, the motor can produce a tension in the rope of the form Fo(1+t/T) where Fo=40 lb. Neglect the inertia of the pulleys and of the robe. If t= 0.5 s. determine the speed of the crate after 1 s. (10 points) M C
