Question

A body of mass 5 kg is moving with a speed 15

cm/s. Find the kinetic energy of the body​

Answer 1

Answer: KINETIC ENERGY = 562.5 JOULES.

Explanation:

given :-

mass (m) = 5kg

speed (velocity) (v) = 15 m/s

we know that,

kinetic energy = 1/2 (m)($v^{2}$)

                        = 1/2 (5) ($15^{2}$)

                        = 1/2 (5) (225)

                        = 1/2 (1125)

                        = 1125/2

                        = 562.5 Joules

$\tt \large{\blue{ \boxed {K_e = 562.5}}}$

$\huge \underbrace \mathfrak \red{\bigstar Explanation}$

${ \bold{ \underline{\purple{\underline{\large{Given : - }}}}}} \:$

Mass (m) = 5kg

Velocity (v) = 15cm/s

$\bf{\purple { Formula \: to \: be \: used \: :- }}$

$\begin{gathered}\begin{gathered}\pink\bigstar\:\bigg\{\:\bf\blue{K_e = \frac{1}{2}×m×v²}\:\bigg\}\:\pink\bigstar \\ \end{gathered}\end{gathered}$

${ \bold { \underline{\large{Solution : \leadsto }}}} \:$

By using Formula:-

$\tt \large {K_e = \frac{1}{2}×m×v²}$

$\longrightarrow \large {K_e = \frac{1}{2}×5×15²}$

$\longrightarrow \large {K_e = \frac{1}{\cancel2}×\cancel5×225}$

$\longrightarrow \large {K_e = 562.5\: \: Ans}$
