Question

. Two people pull on a stubborn mule, as seen from a helicopter in Figure 2.1. Find (a) the single force that is equivalent to the two forces shown, and (b) the force that a third person would have to exert on the mule to make the net force equal to zero.

Answer 1

I don't know what Fig. 2.1 looks like.

Answer 2

single force equivalent of the two forces is a magnitude of 190.1696 N
The direction is 75.9 degrees counterclockwise

the force a 3rd person would have to exert to make the net force zero is 188.48 N
