What is the x component of the resultant force?
SOMEONE ASKED π
What is the x component of the resultant force?
HERE THE ANSWERS π
-
F1) Y = SIN 62 * 8.8 N = 7.77 , -X = COS 62 * 8.8 N = -4.13
F2) -Y = SIN 53.5 * 7 N = -5.63, -X = COS 53.5 * 7N = -4.16
Result = Y = 7.77 + β 5.63 = + 2.14, and X = -4.13 + -4.16 = -8.29
= SQRT (2.14^2 + 8.29^2) = 8.56 N magnitude
r =8.56N @ ARC TAN 2.14 / 8.29 = 14.47 deg above the Negative X axis.

Draw a diagram. Use it to get the +/- signs for each component.
Total of x-components is X where:
X = (-8.80cos(62β°)) + (-7.00cos(53.5β°))
Total of y-components is Y where:
Y = (+8.80sin(62β°)) + (-7.00sin(53.5β°))
||R|| =β(XΒ² + YΒ²)
But youβll have to do the arithmetic!
