A loaded ore car has a mass of 870. 00kg and rolls on rails with negligible friction. It starts from rest and is pulled up a mine shaft by a cable connected to a winch. The shaft is inclined at 28.50° above the horizontal. The car accelerates uniformly to a speed of 2. 20m/s in 10.50s and then continues at constant speed. What maximum power (in W) must the winch motor provide?
