Question

A gun of weight 10kg fires a shot of 0.5gwith velocity 230m/s velocity of recoil gun is

Answer 1

ANSWER

EXPLINATION

let mass of gun be m1=10kg=10000g

let mass of bullet be m2=0.5g

let initial vilocity of gun be u1=0 m/s

let initial vilocity of bullet be u2 =230 m/s

according to law of conservation of momentum

v=m1u1+m2u2

m1+ m2

v=0+0.5×230

10000+0.5

v= 115

10000.5

v=
