Question

gun fires A bullet of mass 5g moving with a velocity 2000 second of force is 1 Newton the number of bullets fired​

Answer 1

Answer:

Explanation:

mass of each bullet = 50g = 0.05 kg

velocity = 1000 m/s

let the number of bullets per second = n

Average force acting on gun = 200N

Rate of change of momentum = force

=> nmv = Average force

=> n × 0.05 × 2000 = 1

=> 100n = 1

=> n = 1/100= 0.01

Bullets per second = 1

bullets per minute = 1× 60 = 60

Thus, 60 bullets per minute were fired
