A car has a potential energy of 2.00x10⁵J when the dar has a speed of 14.0m/s. Calculate the kinetic energy of the car when the car has a speed of 28.0m/s

I assume you mistyped, you meant KEnergy in the first instance, otherwise, it makes no sense. Because KE is dependent on the square of speed, if you double speed, KE goes up by a factor of 4.
yes kinetic energy
