Explanation:

Given

mass of bullet m=7 gm

mass of gun and Puck M=150 gm

speed of gun and Puck is v=0.53 m/s

Let speed of bullet be u

conserving Momentum

initial momentum=Final Momentum

0=Mv+mu

$u=-\frac{M}{m}v$

$u=-\frac{150}{7}\times 0.53=-11.35 m/s$

negative sign indicates that bullet is moving in opposite direction
