today is my paper of this question me also don't know sorry

Answer 2

Answer:

Data:

Mass of bullet = 5 g = 5/1000 = 0.005 kg

Mass of a gun = 5 kg

Velocity of bullet = 500 m/sec

Recoil velocity of the gun = ?

Solution:

Momentum of the system before firing = M x 0 + m x 0

= 0

Momentum of the system after firing = MV + mv

= (5) (V) + (0.005) (100)

= 5V + 0.5

Since,

Initial Momentum = Final Momentum

So,

5 V + 0.5= 0

5 V = - 0.5

V = - 0.5/5

V = - 0.1 m/sec

which is the required recoil velocity of the gun.
