The mass of a body is 65 kg and it's KE IS 812.5 joule . What is volicity

Answer 1

${\red {{\bold{ \huge \dag }}\bold {\huge{{\mathcal {\underline{Answer}}}} \dag}}}$

$\star \: \: \underline \blue{Solution} \blue{ : }$

KINETIC ENERGY OF A BODY IS ,

$\frac{1}{2} m {v}^{2}$

HANCE, COMPARING

$\frac{1}{2} m {v}^{2} = 812.5$

$\bold{\frac{1}{2} m {v}^{2} } = \bold{KE}$

$\longrightarrow \: \frac{1}{2} \times 65 \times {v}^{2} = 812.5$

$\longrightarrow \: {v}^{2} = 25$

$\longrightarrow \bold{ \boxed {\mathfrak{v = 5}}}$
