from figure,
F1x = 5.1*cos(35) = 4.18 N
F1y = 5.1*sin(35) = 2.92 N
F2x = 0
F2y = 5 N
Fnetx = F1x + F2x
= 4.18 + 0
= 4.18 N
Fnety = F1y + F2y
= 2.92 + 5
= 7.92 N
magnitude of net force, Fnet = sqrt(Fnetx^2 + Fnety^2)
= sqrt(4.18^2 + 7.92^2)
= 8.96 N <<<<<<---------Answer
direction : theta = tan^-1(Fnety/Fnetx)
= tan^-1(7.92/4.18)
= 62.2 degrees <<<<<<---------Answer

As you will see in a later chapter, forces are vector quantities, and the total force on an object is the vector sum of all forces acting on it. In the figure below, a force F1 of magnitude 6.10 units acts on an object at the origin in a direction θ = 35.0° above the positive x-axis. A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude...
