A machine gun fires 50gm bullets at a speed
of 1km/s The gunman holding the gun can exert an average force of
180N against the gun Determine the maximum number of bullets he can
fire per minute

Dear student
mass of each bullet=m=50 gm=0
05 kgvelocity of each bullete v=1km/s= 1000 m/sLet n be the number of bullets fired per secondThe change in momentum of the buttelts coming out per second is=Force exerted on gunman =n×0
05×1000=n×50which is equal to 180 NThereforen×50=180n=180/50n≈4Regards

A machine gun fires 50gm bullets at a speed of 1km/s. The gunman holding the gun can exert an average force of 180N against the gun. Determine the maximum number of bullets he can fire per minute.
