Compute work done when a 5 N force acts over 3 m.

Work is found by multiplying the force by the distance the object moves when the force acts in the same direction as the motion. Here the force is 5 N and the object moves 3 m in that direction, so the work done is 5 × 3 = 15 joules. The other values would require a different distance or a force not fully aligned with the motion, but with a force and displacement in the same direction, 15 J is the correct result.
