Question

The gun fires 8 bullets per second into a Target x.if the mass of each bullet in 3g and it's speed 600 ms-1.then calculate the power delivered by bullets.

Answer 1

The power delivered by bullets is 141.12 Watt.

Explanation:

Given that,

Rate of bullet = 8 bullet /s

Velocity = 600 m/s

Mass of bullet = 3 g

We need to calculate the power

Using formula of power

$P=\dfrac{W}{t}$

$P=\dfrac{F\times d}{t}$

$P=mg\times v$

Put the value into the formula

$P=3\times10^{-3}\times9.8\times600$

$P=17.64\ Watt$

We need to calculate the power delivered by bullets

Using formula of power

$\text{ power delivered by bullets}=P\times \text{Number of bullets}$

Put the value into the formula

$\text{ power delivered by bullets}=17.64\times8$

$\text{ power delivered by bullets}=141.12\ Watt$

Hence, The power delivered by bullets is 141.12 Watt.
