PhysicsEasysingle choice

A rifle man, who together with his rifle has a mass of $100 kg$ , stands on a smooth surface and fires 10 shots horizontally. Each bullet has a mass $10 g$ and a muzzle velocity of $800 ms^{- 1}$ . The velocity which the rifle man attains after firing 10 shots is

Options:

Answer:

Solution:

According to law of conservation of momentum, $100 v = - \frac{10}{1000} \times 10 \times 800 i.e., v = 0.8 ms^{- 1}$
