The graph shows three forces, A, B, and C, all acting on an object placed at the origin. A fourth force, F (not pictured), keeps the object at equilibrium.
What is the magnitude of the y-component of force F?
a. 17 N
b. 24 N
c. 48 N
d. 6.0 N
Ay: 30cos35 = 24.57
By: -40sin25 = -16.90
Cy: -50sin40 = -32.14
Resultant y-component force is -24 N
Magnitude = I-24I = 24 N Choice b.
