The helicopter view in the figure below shows two people pulling on a stubborn mule. Assume that F1 is 130 N, and F2 is 65 N. The forces are measured in units of newtons (N).
(a) Find the single force that is equivalent to the two forces shown.
In both magnitude and direction.
(b) Find the force that a third person would have to exert on the mule to make the net force equal to zero.
