Two ropes are attached to the bumper of a car. One person pulls the first rope with a force of 62 pounds at an angle of 38o to the horizontal ground, while another person pulls the second rope with a force of 46 pounds at an angle of 52o to the horizontal ground. The same effect can be produced by a single rope pulling with what force and at what angle to the ground?
