Answer 2

hey

Answer:

a is correct

Explanation:

p = m*v

squaring both sides

$p^{2}$ = $m^{2}$  *  $v^{2}$

and

KE = 1/2 m $v^{2}$

so,

$v^{2}$ = $p^{2}$ / $m^{2}$ .......... 1

$v^{2}$ = KE * 2 / m ............2

from 1 and 2

$p^{2}$ / $m^{2}$ = 2 KE /m

$p^{2}$ = 2 m KE

hence, KE= $p^{2}$ /2m

hope it helps !!!
