Answer:

A . quadruple

Explanation:

the equation of kinetic energy is 1/2mv^2

where m is the mass

and v is the velocity

lets give an example

1/2*1*1^2 = 1/2

and if you double the velocity

1/2*1*2^2

=2

hence 2/(1/2) = 4

this shows that if you double the velocity you quadruple the kinetic energy
