In the 1950s, an experimental train that had a mass of 2.00 104 kg was powered across a level track by a jet engine that produced a thrust of 5.30 105 N for a distance of 509 m. Assume that air resistance is negligible.
(a) Find the work done on the train.
J
(b) Find the change in kinetic energy.
J
(c) Find the final kinetic energy of the train if it started from rest.
J
(d) Find the final speed of the train if there had been no friction.
