Given: "m_{gun}=15\\:\\rm g" "m_{bullet}=2\\:\\rm g" "v_{bullet}=600\\:\\rm m\/s" The law of conservation of momentum says "m_{bullet}v_{bullet}=m_{gun}v_{gun}"Hence, the recoil speed of the gun "v_{gun}=\\frac{m_{bullet}v_{bullet}}{m_{gun}}=\\frac{2*600}{15}=80\\:\\rm m\/s"Recommended textbooks for you  College Physics Author:Raymond A.
