Atruck pulls a trailer at a constant velocity for 100 m while exerting a force of 480 n. calculate the work done. a) 380 j b) 580 j c) 48,000 j d) 4.8 j

Considering the definition of work,

Force is any agent capable of modifying the amount of movement or the shape of material bodies.

So work is defined as a force acting through a distance (or displacement), and is calculated as the product of the component force and the distance. The force can be constant over the distance or vary over the distance.

In mathematical terms, work is defined as

W = F×d

where:

If force is measured in Newtons and distance in meters, then work is measured in units of energy which are joules (J).

In this case, you know:

Replacing in the definition of work:

W= 480 N×100 m

Solving:

W= 48,000 J

Finally, the correct answer is option c): The work done is 48,000 J.
