Two men decide to use their cars to pull a truck stuck in mud. They attach ropes and one pulls with a force of 532 Newtons at an angle of 25 degrees with respect to the direction in which the truck is headed, while the other car pulls with a force of 1003 Newtons at an angle of 20 degrees with respect to the same direction.
