The motor M pulls in its attached rope with an acceleration a, = 9 m/s² . The coefficient of kinetic friction between the crate and the plane is 4k = 0.2. Neglect the mass of the pulleys and rope. (Figure 1) 0 = 30° Part A Determine the towing force exerted by M on the rope in order to move the 80-kg crate up the inclined plane. Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) HẢ ? T= Value Units
