Question 2 5 points Save Answer An object with a mass of 74.0 kg is pulled up an inclined surface by an attached rope, which is driven by a motor. The object moves a distance of 55.0 m along the surface at a constant speed of 3.3 m/s. The surface is inclined at an angle of 30.0° with the horizontal. Assume friction is negligible. How much work (in k]) is required to pull the object up the incline? O 19.9 KJ O 12.9 KJ O 15.9 KJ O 9.9 KJ
