From an automatic gun a man fires 360 bullet per minute with a speed of 360 km/hour. If each weighs 20 g, the power of the gun is

A

600 W

B

300 W

C

150 W

D

75 W

Text Solution

Verified by Experts

The correct Answer is:
A
`P=(KE)/t=(nxx1/2 mv^2)/(t)`
`= (360xx1/2 xx20xx10^(-3)xx(360xx5/18)^2)/60 = 600 W`
