Scientific paper
A laboratory determination has been made of the translational and rotational kinetic energies of the fragments generated by the catastrophic impact of a high speed projectile against a basalt sphere, yielding a maximum rotational/translational kinetic energy value of the order of 0.01. While the value obtained for the asteroid family members, despite the great difference in scale, is similar, it is somewhat lower, perhaps due to the extent to which asteroid family members have been slowed by repeated collisions after the catastrophic disruption of the parent bodies.
