Unformatted text preview: = Anmv 2 where n is the number density of the bullets (bullets per unit volume). The pressure is then p r = F A = nmv 2 = 2 nK , where K = 1 2 mv 2 . Note that nK is the kinetic energy density. Also note that the relation between energy and momentum for a bullet is quite diFerent from the relation between those quantities for an electromagnetic wave....
