Question
± Two Forces Acting at a Point Part A What is the x component of the resultant force? Two forces, F1 and F2, act at a point. F1 has a magnitude of 9.80 N and is directed at an angle of 63.0 above the negative x axis in the second quadrant. F2 has a magnitude of 6.40 N and is directed at an angle of 52.4° below the negative x axis in the third quadrant. Express your answer in newtons.

Hints Submit My Answers Give Up Part C What is the magnitude of the resultant force?Explanation / Answer
PartA) Fx = - F1 cos theta1 - F2 cos theta2
= - 9.80 cos 63 degree - 6.40 cos 52.4 degree
= -8.35 N answer
Part B) Fy = F1 sin theta1 - F2 sin theta2
= 9.80 sin 63 degree - 6.40 sin 52.4 degree
= 3.66 N answer
Part C) magnitude of Resultant force = sqrt (8.35^2 +3.66^2)
= 9.12 N answer
