Which object has the greatest

kinetic energy? (1 point)
a blue car with a
mass of 500 kg
moving at 30 m/s
a yellow car with
a mass of 500 kg
moving at 12 m/s
a red car mass of
500 kg moving at
3 m/s
a green car with
a mass of 500kg
moving at 21 m/s

The object with the greatest kinetic energy is the blue car with a mass of 500 kg moving at 30 m/s. Kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2. Therefore, the blue car has the greatest kinetic energy due to its higher velocity compared to the other cars.
