Answer:
1333.34 kg
Explanation:
Given that,
The mass of the gun, m = 8 kg
Speed of the bullet, V = 50 m/s
The recoil speed of the gun, v = -0.3 m/s
We need to find the mass of the bullet. Using the conservation of momentum to find it. Let M is the mass of the bullet.
[tex]mv=MV\\\\M=\dfrac{mv}{V}\\\\=\dfrac{50\times 8}{0.3}\\\\=1333.34\ kg[/tex]
So, the mass of the bullet is 1333.34 kg.
