Two forces, F⃗ 1 and F⃗ 2, act at a point, as shown in the picture. (Figure 1) F⃗ 1 has a magnitude of 9.60 N and is directed at an angle of α = 65.0 ∘ above the negative x axis in the second quadrant. F⃗ 2 has a magnitude of 6.80 N and is directed at an angle of β = 53.1 ∘ below the negative x axis in the third quadrant.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
