A 2.0kg object is moving at 3 m/s. A

4-N force is applied in the direction of motion and then removed after the object has traveled an additional 5m. The work done by this force is.

Would the answer be simply:
W=F*d= (4* 5m)= 20N and you only take the information concerning that force.
Thank you

That is it. Work is force * distance.

Yes, you are correct! To calculate work, you multiply the force applied in the direction of motion by the distance over which the force is applied. In this case, we have a force of 4 N applied over a distance of 5 m.

So, the work done by this force would be:

Work = Force * Distance
= 4 N * 5 m
= 20 N·m (or Joules)

Therefore, the work done by this force is 20 Joules.
