2 The helicopter view in the figure shows two people pulling on a stubborn mule. The person on the right pulls with a force F of magnitude 89.4 N and direction of e, = 70.0°. The person on the left pulls with a force F, of magnitude 85.3 N and direction of 82 - 80.00 1 09 (a) Find the single force that is equivalent to the two forces shown. The forces are measured in units of newtons (symbolized N). 7.97 x Use definitions of the sine and cosine to determine the components. Ni + 165 Nj 180 (b) Find the force that a third person would have to exert on the mule to make the resultant force equal to zero. X Given that F, +F+F, = 0, how is F, + related to the sum of F, and F,? Ni+ 87 X Given that F,+F,+F, = 0, how is F, + related to the sum of F, and F, Nj + 2
