Question

Two forces, F? 1 and F? 2, act at a point, as shown in the picture. (Figure 1) F? 1 has a magnitude of 8.20Nand is directed at an angle of ? = 57.0? above the negative x axis in the second quadrant. F? 2 has a magnitude of 6.60N and is directed at an angle of ? = 52.2? below the negative x axis in the third quadrant

A. What is the x component Fx of the resultant force?

B. What is the y component Fy of the resultant force?

C. What is the magnitude F of the resultant force?

D. What is the angle ? that the resultant force forms with the negative x axis? In this problem, assume that positive angles are measured clockwise from the negative x axis.

Explanation / Answer

Because it makes the computations much simpler, convert both angles to be measured counterclockwise from the positive x axis:
? = 180
