The kinetic energy is quadrupled ie becomes 4 times when momentum is doubled... Approve it if the answer is ri8

kinetic energy of object = ½ mv2
 
when the momentum of object is doubled,
then, kinetic energy of object = ½ m(2v)2
                                           = ½ 4mv2
                                           = 4[1/2mv2]
so the momentum of an object after doubled is 4 times graeter.

The momentum is doubled. But it`s not mentioned that which quantity is changed to make it double whether velocity or mass. So it can`t be concluded.
