Question

The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take F1 = 110 N and F2 = 79.0 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.

(a) Find the single force that is equivalent to the two forces shown.
magnitude
direction


(b) Find the force a third person would have to exert on the mule to make the net force equal to zero.
magnitude

direction

Answer 1

It is B, because the force vector makes a angle ot 60 degrees which is a proportional relationship to the force vector of 1.

Step-by-step explanation:

The road marked with force F2 is 75 degrees, dividing that results in a magnitude of a single force that is equivalent to the two force shown in the magnitude and direciton.
