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? F = 3 x20x10x 300 = 24N A satellite in a force-free space onary interplanatary =٧ • The acceleration dust sweeps stari at a rate of of the satellite is? ? if a bomb two fragments initially at rest is exploade 1010 with masses are in the ratio 2:3 if first fragment moving with velocity 6mis towards north and direction of then what velocity? is the magnitude
