Questions
A machine gun is mounted on a 2 quintal vehicle on a horizontal smooth road. (Friction negligible). The gun fires 10 bullets per second with a velocity of 500 no/s. If the mass of each bullet be 10 g, what is the acceleration produced in the vehicle?
detailed solution
Correct option is E
Momentum carried by each bullet = m v = (0.010 x 500) kg.m/s = 5 kg.m/sNow force = chan8e in momentum in 1s = 5 x 10N = 50N∴ Acceleration =(20/200)m/s2 =25cm/s2.Talk to our academic expert!
