Question

find kinetic energy ​

Answer 1

$for \: kinetic \: energy \: we \: have \\ \frac{1}{2} m {v}^{2} \\ now \: putting \: value \\ \frac{1}{2} \times 500 \times {v}^{2} = 500 \\ {v}^{2} = 2 \\ v = + - \sqrt{2} m {s}^{ - 1}$

Answer 2

Answer:√2

Explanation:

Use the formula of K.E=1/2m(v^2) where m is mass od body and v is velocity join substitution u will get v=√2
