• what with the "heavy object" in the table under "Typical projectile speeds" ? doesn the weight have anything to do with the speed ?

No it doesn't -- I'm changing it. Zorath 15:07, 17 July 2006 (UTC)

Was the heavy object for something falling? if so would that mean "ignore air resistance"? raptor 02:42, 16 August 2006 (UTC)

[edit] A question concerning kinetic weapon destruction

I am writing a hard SF novel which postulates a 12 gram object propelled at near relativistic speeds==10% c. Could anyone give the kinetic energy transfer involved in joules? I need to get a handle on the destructive power of such a weapon. Are we speaking of a planet-buster?

Regards, Scott
