Question

Derive an expression for kinetic energy and momentum of a body?

Answer 1

$k = \frac{1}{2} m {v}^{2} \\multiplying \: and \: dividing \: by \: m \\ k = \ \ \frac{1}{2} \frac{ {m}^{2} {v}^{2} }{m} \\ k = \frac{1}{2} \frac{( {mv}^{2}) }{m} \\ k = \frac{1}{2} \frac{ {p}^{2} }{m}$Hey here is your answer ^-^
