A gun fires 8 bullets per second into a target X If the mass of each bullet is 3 g and its speed `600ms^(-1)`. Then, calculate the power delivered by the bullets

Text Solution

Verified by Experts

`P=8xx("Kinetic energy of each bullets per second")`
`=8xx1/2xx(3xx10^(-3))xx(600)^(2)=4320W , P=4320kW`
