mass of object = m

Let initial velocity of object = v

ke =  \frac{1}{2} m {v}^{2}

if velocity is doubled,

new velocity = 2v


new \: ke =  \frac{1}{2} m {(2v)}^{2}  = \frac{1}{2} m  \times {4v}^{2}

new \: ke = 4 \times  \frac{1}{2} m {v}^{2}  = 4 \times ke

Thus the kinetic energy will be 4 times if the velocity is doubled.
