Blasting Asteroids

 Imagine you are in the future and an asteroid is on a trajectory to hit Earth. You and your team get on a spaceship and blast off to save the Earth. The spaceship is equipped with a laser that can disintegrate half the asteroid. The asteroid has a mass of two million kg and a speed of fifteen thousand meters per second. What is the force of the asteroid before and after the laser blast? Why is the force less after the laser blast?

Consider the following

 If you could break one of Newton's Laws of motion which law would you break? What would you be able to do? Would this mean you have a super power?
