156. To put it simply, its not the fall that kills you, its the stop at the end...

or, to reverse it, no matter your velocity, its a ratio between the acceleration and time it took to reach that velocity that matters. A human body, to give an example, is much more delicate than an asteroid, yet we can safely accelerate it from apparent rest on Earth to a speed several times faster than a speeding bullet on the way to the Moon. We've done it, several times. Those same forces have the same affect on asteroids as they do on people. Yet, if you were to fire a human body out of a cannon at those same speeds, but at a much higher acceleration, I believe the term liquefaction comes to mind.

The idea is not to shock the asteroid into breaking apart, and frankly most of them aren't geologically unstable, that would imply some type of geologic activity, which they do not have, they are inert pieces of rock, some are literally loose gravel piles of smaller bits of rock that are barely held together by gravity, those we wouldn't even be able to land on to do much work, much less move them, at least not without modifying their properties.

In addition, we already have the tools to figure out the properties of any asteroid we can examine, including density, material its made out of, fracture lines, etc. We actually have figured out the properties of many of these bodies already.
