A space ship of mass 5.00 ×104 kg is traveling at a speed 1.15× 104 m/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 ×105 N, the ship move a distance of 2.50 ×106 m in the direction of the force of the engine. Determine the final speed of the ship using the work-energy theorem.
