Determine the amount of work done by the applied force when a 87 N force is applied to move a 15 kg object a horizontal distance of 4.5 meters at a constant speed.

391.5 J

Explanation:

The amount of work done can be calculated using the formula:

Looking at the formula, we can see that the mass of the object does not affect the work done on it.

Substitute the force applied and the displacement of the object into the equation.

The amount of work done on the object is 391.5 J in order to move it 4.5 meters with an applied force of 87 Newtons.
