An object with a mass of 66.0 kg is pulled up an inclined surface by an attached chain, which is driven by a motor. The object moves a distance of 70.0 m along the surface at a constant speed of 2.9 m/s. The surface is inclined at an angle of 30.0° with the horizontal. Assume friction is negligible. (a) How much work (in kJ) is required to pull the object up the incline? kJ (b) What power (expressed in hp) must a motor have to perform this task? hp
