To calculate the work done by force F1, we need to consider the displacement of the body in the direction of F1. Since the body is moving in the direction of the net force, we can assume that F1 is the net force and F2 is canceled out.
Given: F1 = 5 N (net force) F2 = 15 N (opposite direction) Displacement = 5 m
The work done by a force is given by the formula:
Work = Force × Distance × cosθ
In this case, the angle θ between the force and the displacement is 0 degrees because they are in the same direction (cos 0 = 1).
Plugging in the values:
Work = F1 × Displacement × cosθ = 5 N × 5 m × cos 0 = 25 Nm
Since work is measured in joules (J), we can rewrite it as:
Work = 25 J
Therefore, the work done by force F1 is 25 joules (J).
