Two forces, F⃗ 1 and F⃗ 2, act at a point, as shown in the picture. (Figure 1) F⃗ 1 has a magnitude of 8.20N and is directed at an angle of α = 55.0∘ above the negative x axis in the second quadrant. F⃗ 2 has a magnitude of 6.40N and is directed at an angle of β = 53.4∘ below the negative x axis in the third quadrant.
a)
What is the x component Fx of the resultant force?
Express your answer in newtons.
B)
What is the y component Fy of the resultant force?
Express your answer in newtons.
C)
What is the magnitude F of the resultant force?
Express your answer in newtons.
D)
What is the angle γ 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.
Express your answer in degrees.
