Question

12. Bullets of mass 40 g each are fired from a machine
gun with a velocity of 103 m/s. If the person firing
the bullets experience an average force of 200N,
then the number of bullets fired per minute will be-
(1) 300 (2) 600 (3) 150 (4) 75​

Answer 1

Answer:

option 1 is correct, 300

Explanation:

t = 1 min = 60 sec

avg force = no. of bullet*mass*speed/t

200 = n * 40*10^-3*10^3/60

n = 5*60 = 300 sec
