given:
mass of shell= 1.5 kg
velocity of shell= 150km/s
=150*1000m/s
recoil velocity= 1.5 m/s
mass of shell* velocity of shell= mass of gun* recoil velocity
1.5 * 150*1000= m*1.5
mass of gun =1.5 x 150x1000/ 1.5
mass= 150000kg
mass of shell= 1.5 kg
velocity of shell= 150km/s
=150*1000m/s
recoil velocity= 1.5 m/s
mass of shell* velocity of shell= mass of gun* recoil velocity
1.5 * 150*1000= m*1.5
mass of gun =1.5 x 150x1000/ 1.5
mass= 150000kg
