Increase 4 times
Because velocity after increase is doubled to initial velotial. And velocity in the kinetic energy is squared, so the car’s kinetic energy after increase velocity equal 4 times the initial car’s kinetic energy

The kinetic energy would be increased by a factor of 4 if the speed is doubled.

Kinetic energy is the energy that an object possesses as a result of its motion. It is given by:

Kinetic energy (KE) = (1/2) * mass (m) * [velocity (v)]²

KE = (1/2)mv²

For a car travelling at 12 m/s:

KE = (1/2)m(12²) = 144 * (1/2)m

If the speed is doubled to 24 m/s, the new kinetic energy (KE'):

KE' = (1/2)m(24²) =4 * 144 * (1/2)m = 4 * KE
