An average force of 125 N is applied on a machine gun firing bullets each of mass 10 g at the speed of 250 m s -1 to keep it in position. The number of bullets fired per second by the machine gun is :
Text Solution
Verified by ExpertsThe correct answer is:
A
The formula to calculate the net momentum of the gun and bullet system can be written as
F = nmv ...
Substitute the values of the known parameters into equation and solve to calculate the required number of bullets.
n = 50
