    Physics, The Work-ENERGY
    A space ship of mass 5.00 × 18*4 kg is traveling at a speed 1.15 × 10*4 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 × 10*5 N, the ship moves a
    distance of 2.50 × 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.
    (b) Determine the final speed of the ship using the kinematic equations.

    1. Work out the kinetic energy of the space ship.
    Work out the work done by the ship
    Work out the total energy the ship possesses.
    Work out the speed of the ship using .

    2. The initial speed is 1.15 x 10^4 m/s.
    Find the acceleration of the ship using F = ma
    Use to find the final speed of the ship. (v = final velocity, u, the initial velocity, a the acceleration and s the displacement)
