A pulley mаde up оf а sоlid disk is wоund with а light rope. Suppose the rope is pulled by a net force of 50.0 N such that the angular speed starts to increase at a steady (uniform) rate. The radius of the pulley is 0.5 m. If the moment of inertia of the pulley is 2.0 , and the system started from rest, calculate the angular speed of the pulley after 2.5 revolutions. Use three significant digits please.
