A machine gun fires bullets of mass 30 ~g with velocity of 1000 ~m / s . The man holding the gun can exert a maximum force of 300 ~N on it. How many bullets can he fire per second at most?
Options
- A3
- B6
- C10
- D9
Correct answer
C. 10
Step-by-step solution
Momentum of bullets per second: P = nmv According to Newton's second law of motion, aligned F & = dp dt = d ( nmv ) dt dn dt & = F mv & = 300 0.03 1000 & =10 aligned
