A machine gun is mounted on a 2000 kg car on a horizontal frictionless surface. At some instant the gun fires bullets of mass 10 gm with a velocity of 500 m/sec with respect to the car. The number of bullets fired per second is ten. The average thrust on the system is
Text Solution
Verified by ExpertsThe correct answer is:
B
u = velocity of bullet
Mass thrown per second by the machine gun
= Mass of bullet × Number of bullets fired per second
Thrust
