I'm having trouble with where to begin with this question, if anyone has guidance I'd be grateful. A space ship of mass 5.00 x 10^4 kg is travelling at a speed 1.15 x 10^4m/s in outer space. Except for the force generated by its own engine, no other force acts on the ship. As the engine exerts a constant force of 4.00 x 10^5 N, the ship moves a distance of 2.50 x 10^6 m in the direction of the force of the engine. a) Determine the final speed of the ship using the work-energy Theorem.
