The correct answer is the blue car with a mass of 500 kg moving at 30 m/s.
To calculate kinetic energy, we use the formula:
Kinetic energy = (1/2) * mass * velocity^2
Plugging in the values for each car, we get:
Blue car: (1/2) * 500 kg * (30 m/s)^2 = 225,000 J
Green car: (1/2) * 500 kg * (21 m/s)^2 = 110,250 J
Yellow car: (1/2) * 500 kg * (12 m/s)^2 = 36,000 J
Red car: (1/2) * 500 kg * (3 m/s)^2 = 2,250 J
Therefore, the blue car has the greatest kinetic energy with a value of 225,000 J.
