A bullet of mass with a a speed sof gun bog fired by a gun of lokg 2000 m/s : find recoil velouty. ansvg -3 =100×10×2000 10 = -20m/s Before firing 46=0 mgvg + mgvg = -movb Ng= mg Pbf Coolest seopa9) 0 = 192 ? A gun of mass The mass Velocity of quired to of the 10 kg fires each bullet 4 bullet/second. 209 and the bullet 15 300m/s. The force re- hold the gun while firing is? m=10kg n= 4 mass of cach bullet = 20gm SO 20x4=80 V=Velocity of the buller?
