Question

(ii)

A police recruit, while training, shot at a stationary target of mass 5.0 kg, with a bullet of mass 0.1 kg. The target was mounted on low-fiction wheels and as soon as the bullet struck the target, the target with the embedded bullet sped off with a velocity of 6.0 ms.

Calculate the velocity of the bullet just before it hit the stationary target.​

Answer 1

Answer:

Let the recoil velocity of gun be V.

Mass of gun M

gun

=5.0 kg

Mass of bullet M

bullet

=0.01 kg

Velocity of bullet V

bullet

=250 m/s

Initial momentum of the system P

i

=0

Applying the conservation of linear momentum : P

f

=P

i

Or M

gun

V+M

bullet

V

bullet

=0

Or 5×V+0.01×250=0

⟹ V=−0.5 m/s
