Question

Calculate the kinetic energy of a body of mass 2 kg moving with a velocity of 0.1 metre per second

Answer 1

HEY BUDDY .......
HERE IS UR ANSWER........

FOR CALCULATING KINETIC ENERGY OF AN OBJECT THE FORMULA IS 1/2×m×v^2

SO, KINETIC ENERGY OF THE BODY = 1/2×2×0.1 = 0.1 J

THEREFORE , KINETIC ENERGY OF THE OBJECT IS 0.1 J

HOPE YOU UNDERSTAND ✨ ✨

Answer 2

⠀

$\huge\sf{\underline{\underline{Solution:-}}}$

⠀

$\sf{\underline{\underline{Answer-}}}$

⠀

The kinetic energy of the body is 0.01 joule.

⠀

$\sf{\underline{\underline{Explanation-}}}$

⠀

As we know, the formula of kinetic energy is:

⠀

$\begin{gathered}:\implies\sf Kinetic\: Energy=\dfrac{1}{</p><p>2} \: {mv}^{2} \end{gathered}$

⠀

Here, ⠀⠀⠀⠀⠀⠀Mass, m = 2kg

⠀

And, ⠀⠀ ⠀⠀⠀⠀Velocity, v = 0.1 m/s

⠀

$\sf{\underline{\underline{Putting\:the\:values-}}}$

⠀

$\begin{gathered}:\implies\sf Kinetic\: Energy=\dfrac{1}{</p><p>2} \: \times 2 \times ( {0.1)}^{2} \end{gathered}$

⠀

$\begin{gathered}:\implies\sf Kinetic\: Energy=\dfrac{1}{</p><p>2} \: \times 0.1 \times 0.1\end{gathered}$

⠀

$\begin{gathered}:\implies\sf Kinetic \: energy=0.1 \times 0.1\end{gathered}$

⠀

$\begin{gathered}:\implies\sf Kinetic \: energy=0.01J\end{gathered}$

⠀

Thus, the kinetic energy of the body is 0.01 joule.
