The helicopter view in figure below shows two people pulling on a stubborn mule. Find (a) the single force that is equivalent (resultant) to the two forces shown, and (b) the force that a third person would have to exert on the mule to make the resultant force equal to zero. The forces are measured in units of newtons (abbreviated N). F1= F2 = 120 N 80 N 75.0 60.0
