The force acting on the path is 2 km. In the direction of movement, I performed work of 300 kJ.

The force acting on the path is 2 km. In the direction of movement, I performed work of 300 kJ. determine the modulus of this force.

S = 2 km = 2000 m.
A = 300 kJ = 300000 J.
F -?
A = F * S * cosα, where F is the force that performs the work A, S is the distance the body has moved under the action of the force F, α is the angle between the force F and the displacement S.
Since the force F performs work in the direction of displacement S, then α = 0, cos0 = 1.
A = F * S.
F = A / S.
F = 300000 J / 2000 m = 150 N.
Answer: F = 150 N.
