We have,
m= mass of bullet
v = velocity of bullet
M= Mass of Gun
V = Velocity of Gun.
Impulse on Bullet,I= mv-0 ..... (1)
We know,
By Conservation of momemtum as initial momemtum is 0.
0= mv +MV
v= -mv/M
v= -200/10
= - 20m/s
m= mass of bullet
v = velocity of bullet
M= Mass of Gun
V = Velocity of Gun.
