A rigid body moves a distance of 10m along a straight line under the action of a force 5N. If the work done by this force on the body is 25 joules, the angle which the force makes with the force makes with the direction of motion of the body is:

Explanation

To solve the problem, we need to find the angle \( \theta \) that the force makes with the direction of motion of the body. We can use the formula for work done by a force:

\[ W = F \cdot s \cdot \cos(\theta) \]

Where:
- \( W \) is the work done (in joules),
...
