Answer 1

Answer:

$\Huge{\mathscr{\fcolorbox {blue}{aqua}{\color {purple}{Answer}}}}$

$\underline\blue{\boxed{\dag K.E\: = \: \frac{1}{2} m {v}^{2}\dag}}$

We know that,

$\underline\blue{\boxed{\dag Momentum, \: p \: = \: mv \dag}}$

KE = $\frac{ {p}^{2} }{2}$

${p}^{2} = 2 \times 10 \times 500$

${p}^{2} = 10000$

p = $\sf\green{\boxed{100}}$
