Question:
I am a Physics teacher in Albuquerque New Mexico and one of two sponsors of supercomputing contest teams here. We have a team whose project is doing a simulation of Hermes collision with the earth. They are now attempting to see if they can simulate diverting such a collision with the explosion of an atomic device. Their program involves differential s equations with two dimensional variable variables I for velocity and acceleration. Is it a reasonable first approximation to translate the energy yield of such a bomb into kinetic energy and the fractions of this energy in the direction x and y into the velocities at the time of the explosion into velocity components? The fraction determined by integration over a solid angle.



Replies:
Yes, that sounds like a reasonable approximation. You might attempt to get into a more detailed picture of the explosion (quantity of mass in the bomb, what exactly it does to the asteroid - for example splitting it into several pieces is an option perhaps) to be sure you are doing something reasonable.
