A rifle of 20 kg mass can fire 4 bullets per second. The mass of each bullet is 35×10⁻³kg and its final velocity is 400ms⁻¹ . Then what force must be applied on the rifle so that it does not move backwards while firing the bullets
Added by Arch K.
Step 1
Given that the mass of each bullet is 35×10^-3 kg, the final velocity of each bullet is 400 m/s, and 4 bullets are fired per second, the total momentum of the bullets before firing is: Total momentum = (mass of one bullet) x (final velocity of one bullet) x Show more…
