Question

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

Quantrex Academy · Accepted Answer

Correct answer: B. 0.8 ~ms ⁻¹

According to law of conservation of momentum, array l 100 v =- 10 1000 10 800 i.e., v =0.8 ~ms ⁻¹ array
