An automatic gun fires 360 bullets per minute with a speed of 360 kg/h. If each bullet weighs 20 g, the power of the gun will be

A

600 W

B

300 W

C

150 W

D

1200 W

Text Solution

Verified by Experts

The correct Answer is:
A
Power = `(n xx 1/2 mv^2)/(t)`
`= (360 xx 1/2 xx 20 10^(-3) xx (100)^2)/(60)`
`= 600 W`
