Explanation:

$\huge\red{\underline{\underline{ \bf Question:-}}}$

A ball weighing 5kg has a kinetic energy 16 joule when it's speed

$\huge\red{\underline{\underline{ \bf Answer:-}}}$

$\huge\blue{formula} \: \\ \\ \leadsto kinetic \: \: energy = \frac{1}{2} \times m \times {v}^{2} \\ \\ where \\ m = mass \\ \\ v = velocity \\ \\ \leadsto kinetic \: \: energy = \frac{1}{2} \times m \times {v}^{2} \\ \\ \implies 16 = \frac{1}{2} \times 5 \times {v}^{2} \\ \\ \implies {v}^{2} = \frac{32}{5} \\ \\ \implies v = \sqrt{6.4} \\ \\ \huge\boxed{ \implies v = 2.52 \: m {s}^{ - 1}}$
