Question: If an asteroid is spinning, would its angular momentum be
translated into explosive energy upon impact? If so, how much would a 3
km body tumbling at 1 rotation/10 minutes add to the impact from its

>From long ago talk about the kinetic energy of an disintegrating
flywheel, would it be possible to create flywheel warheads? If one used
a mass driver on the moon as a cannon (a la TMIAHM), how much kinetic
energy would be added to its impact by, say, a 300 rpm spin?
