In the 1950s, an experimental train that had a mass of 2.50 x 104 kg was powered across a level track by a jet engine that creates a thrust of 5.00 x 105 N for a distance of 509 m.

1. Discover the work done on the train.

2. Discover the change in kinetic energy.

3. Find the final speed of the train if there were no friction.

4. Find the final kinetic energy of the train if it started from rest.
