Question: If a force of 15 N is applied at an angle of 60° to the horizontal while moving an object 4 m, what is the work done by the force?

Options:

Correct Answer: 120 J

Solution:

Work done = F × d × cos(θ) = 15 N × 4 m × cos(60°) = 15 N × 4 m × 0.5 = 30 J.

Correct Answer: 30 J

Work Done – Work is calculated as the product of the force applied, the distance moved in the direction of the force, and the cosine of the angle between the force and the direction of movement.
