since kinetic energy is proportional to the square of velocity it is multiplied by 2 x 2 which is 4

momentum is doubled, kinetic energy is quadrupled
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.

It doubles.
Kinetic energy is proportional to velocity2, so if velocity is multiplied by four the kinetic energy is multiplied by sixteen
The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time.
The kinetic energy would be quadrupled, and the momentum would be doubled.
If the velocity of Earth were to double, it would have 4 times the kinetic energy. Twice the current kinetic energy would already be enough to catapult the Earth away from the Sun - never to return.
If the velocity is doubled, then the kinetic energy increases by 4 times
Twice the mass --> twice the kinetic energy.
Let's see. Mass constant. 625000 Joules = 1/2(500 kg)V2 1250000 Joules = 500V2 2500 = V2 50 meters/second = velocity ==================================== The velocity doubles if KE doubles.
