Here, $\mathrm{n}=\frac{360}{60}=6$ bullets s ${}^{-1}$ Velocity, $\mathrm{v}=600{\mathrm{ms}}^{-1},\mathrm{m}=$ ? Power of gun = Power of bullets $5.4\times 10^3=\frac{1}{2}(\mathrm{nm}){\mathrm{v}}^2$ $2\times 5400=6\times \mathrm{m}(600{)}^2$ or $\begin{array}{rl}\mathrm{m}& =\frac{2\times 5400}{6\times 600\times 600}\mathrm{kg}\\ & =\frac{1}{200}\mathrm{kg}=\frac{1000}{200}\mathrm{g}=5\mathrm{g}\end{array}$
