Calculating Work Done on a Train with Jet Engine Thrust?

In summary, a train with a mass of 18200 kg was powered by a jet engine with a thrust of 521000N for 444m on a level track. The work done on the train can be found using the equation W=Fd. However, if an incorrect answer was received, it may be due to a mistake in the problem statement or calculation.

A train that had a mass of 18200 kg was powered across a level track by a jet engine that produced a thrust of 521000N for a distance of 444m. Find the work done on the train.

I thought this was pretty straightforward; however, it's apparently not.

I used W=Fd, but I got the wrong answer. Can anyone help me?

You should have gotten the right answer with that approach. Maybe the answer in your book is wrong.

It's through an online server (U Texas).

OK, then tell me:

1.) Did you post the exact problem statement?

2.) What answer did you get?

3.) What feedback did you get from the server?

Nevermind! I left off a zero! Thanks for your help though.
 

Related to Calculating Work Done on a Train with Jet Engine Thrust?

1. How is work done on a train calculated?

The work done on a train is calculated by multiplying the force applied to move the train by the distance the train travels.

2. What factors affect the work done on a train?

The factors that affect the work done on a train include the mass of the train, the speed of the train, and the incline or decline of the track.

3. Can work be done on a train without an external force?

No, work cannot be done on a train without an external force. The train needs a force, such as an engine or an external push, to move and do work.

4. Does the direction of the train affect the work done?

Yes, the direction of the train does affect the work done. Work is a scalar quantity, meaning it only has magnitude and not direction. However, the displacement of the train, which is a vector quantity, does have direction and affects the calculation of work.

5. How does friction affect the work done on a train?

Friction can affect the work done on a train by adding an opposing force that must be overcome. This means more work is required to move the train, as some of the force is being used to overcome frictional forces.
