Correct Answer: becomes 4 times


Solution : The correct option is becomes 4 times .

Velocity and momentum are directly related. An object's velocity is twice as high if its momentum doubles, but its mass does not (the object's velocity stays below the speed of light). When the velocity doubles, the kinetic energy multiplies by four.
