(Take F1 = 147 N and F2 = 63.0 N) An illustration shows the helicopter view of a mule being pulled along a forked road in two directions by two men. An x y coordinate system is overlaid on the image, with the origin at the mule's nose, and the mule facing in the positive y-direction. The man on the right is pulling the mule toward the right-side forked road with a force F1. This force vector makes an angle of 60.0° with the horizontal drawn right in front of where the mule is standing. The man on the left is pulling the mule toward the left-side forked road with a force F2. This force vector makes an angle 75.0° with the horizontal.
