Respuesta :

So the formula for kinetic energy is 1/2 mv^2

The answer is 450.

I hope this helps you!

Answer:

The kinetic energy is 450 J.

(C) is correct option

Explanation:

Given that,

Speed = 300 m/s

Mass of bullet = 10 g

We need to calculate the kinetic energy

Using formula of kinetic energy

[tex]K.E=\dfrac{1}{2}mv^2[/tex]

Where, m = mass of bullet

v = speed of bullet

Put the value into the formula

[tex]K.E=\dfrac{1}{2}\times10\times10^{-3}\times(300)^2[/tex]

[tex]K.E=450\ J[/tex]

Hence, The kinetic energy is 450 J.
