Part A) If theta= 58 degrees and F=500 N, determine the magnitude of the resultant force. Part B) If theta= 58 degrees and F=500 N, determine the resultant force direction, measured counterclockwise from the positive x axis.
Resultant force = √(F12+F22+2F1F2 cos θ )= √( 2500 + 4900 + 2*500*700* cos 137 = 477.55 N
OR
horizontal force = 700 cos 15 - 500 cos 58 = 411.19 N
also net vertical force = 700 sin 15 - 500 sin 58 = -242.85 N
Resultant = 477.55 N
Angle = inverse tan (242.85 / 411.19) = 30.57 degrees
so required angle = 360 - 30.57 = 329.43 degrees.
