Two people are pulling a mule, assume the F1 is 110 N and F2 is80 N. I found the single force that is equivalent to the two forcesfor magnitude and direction but I need to find out the force that a third person would have to exert on the mule to make the netforce equal to zero for the direction in degrees.
