    kinetic/potential energy (physics)?

    In the 1950s, an experimental train that had a mass of 2.05 multiplied by 104 kg was powered across a level track by a jet engine that produced a thrust of 4.85 multiplied by 105 N for a distance of 509 m. Assume that air resistance is negligible. (a) Find the work done on the train...
