Question

Give
sofontific reason for the following
statement
when a bullot is fixed is fired foom
о a gun
the gun secolis.​

Answer 1

Explanation:

This can be verified using law of conservation of momentum.

Initially gun and bullet is at rest, so momentum of system before firing is 0

but after firing the gun, both bullet and gun aquires some velocity.

Acc. to Law of conservation of momentum,

momentum before firing =momentum after firing

0 = mbvb +mgvg

so, vg = - mbvb/mg

This negative sign shows that the direction of velocity of gun and bullet is in opposite direction.

Hence, as the bullet moves forward, gun moves backward or recoils.
