Questions
A machine gun is mounted on a 200 kg vehicle on a horizontal smooth road (friction negligible). The gun fires 10 bullets per second with a velocity of 500 m/s. If the mass of each bullet be 10 g, what is the acceleration produced in the vehicle ?
detailed solution
Correct option is A
The momentum carried by each ball=m v = 0.010 x 500 = 5 kg m/s∴ Force = change in momentum in one second=5x10=50NSo, acceleration=50200=25cm/s2Talk to our academic expert!
