2. 013.5 points I Previous Answers SerEssen1 3.P014. My Notes Ask Your Tea The helicopter view in Figure P3.14 shows two people pulling on a stubborn mule. Assume that F1 is 120 N and F2 is 80 N. The forces are measured in units of newtons (N). Find the following 75,0 60,0 Figure P3.14 (a) The single force that is equivalent to the two forces shown. 6171.93 Your response differs significantly from the correct answer.

Explanation / Answer

Force along horizontal direction,

Fx = (120 x cos60) - (80 x cos75) = 39.29 N

Force alone vertical direction,

Fy = (120 x sin60) + (80 x sin75) = 181.20 N

Force, F = sqrt(Fx^2 + Fy^2) = 185.41 N

Direction, theta = arctan (Fy/Fx) = 77.77 degree

B)

Net force acting must be equal to third force to make net force equal to zero.

So magnitude is 185.41 N

Direction, theta = 180 + 77.77 = 257.77 degree
