If velocity of a body is twice of previous velocity, then kinetic energy will become
$2 $ times
$\frac{1}{2}$times
$4$ times
$1 $ times
If velocity of a body is twice of previous velocity, then kinetic energy will become
Kinetic energy = $\frac{1}{2}m{v^2}$
K.E.$ \propto v_2$
If velocity is doubled then kinetic energy will become four times.
