I' ll Bite . . . what good is speed if you don' t have the weight to penetrate.

Light travels at 186,000 miles per second but it can' t penetrate an opaque object without some hole to get through. It is extremely powerful and potentially dangerous . . . but it has No relative MASS.

One could also have a one ton peice of rock but without a velocity acting on it, it will go nowhere and penetrate nothing.

Considering the two scenarios given X Mass and Y velocity and you achieve a force in ft-lbs that is capable of penetarting.

What I am trying to say is that you can have all the speed in the world but without mass, that' s all you have. YOU NEED A COMBINATION OF BOTH TO DO THE JOB!

BTW, I agree with Trapper Dave.
