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

600W

B

300W

C

150W

D

1200W

Text Solution

Verified by Experts

The correct Answer is:
A

Power `=(n xx (1)/(2) mv^(2))/(t)`
`=(360 xx (1)/(2) xx 20 xx 10^(-3) xx (100)^(2))/(60)`= 600W
