I'm trying to calculate (for fun) a comparison between a kinetic impactor and an H-bomb.
I would assume this to be a fairly straight forward problem involving kinetic energy and a table of various H-bomb energy outputs. However, I was thinking about this and realized that assuming a fairly small mass (say 10kg) the velocity required would be approaching relativistic speeds.
I was thinking about this in the context of destroying asteroids, so I was also worrying about the impact angle and whether the target would absorb some of the energy by rotating about some axis. I decided that at the velocities involved and the energies released it would probably not matter.
However, I am not sure. Would "impact angle / distance from center of mass" be something I should worry about?
