Calculating Work Done on a Train with Jet Engine Thrust?

[missyjane]

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.
