A spaceship of mass 5.00 x 104 kg is travelling at a speed 1.15 x 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 x 105 N, the ship moves a distance of 2.50 x 106m in the direction of the force of the engine. a. Determine the final speed of the ship using the work-energy theorem. b. Determine the final speed of the ship using kinematic equations
