which object has the greatest kinetic energy a a green car with a mass of 500 KG moving at 21 MSB a yellow car with a mass of 500 KG moving at 12 MSC a blue car with a mass of 500 KG moving at 30 MS or D a red car with a mass of 500 KG moving at 3MS
The object with the greatest kinetic energy is the blue car with a mass of 500 kg moving at 30 m/s.
To calculate the kinetic energy of each object, you can use the formula:
Kinetic Energy = 0.5 * mass * velocity^2
For the blue car:
Kinetic Energy = 0.5 * 500 kg * (30 m/s)^2
Kinetic Energy = 0.5 * 500 kg * 900 m^2/s^2
Kinetic Energy = 225,000 J
For the green car:
Kinetic Energy = 0.5 * 500 kg * (21 m/s)^2
Kinetic Energy = 0.5 * 500 kg * 441 m^2/s^2
Kinetic Energy = 110,250 J
For the yellow car:
Kinetic Energy = 0.5 * 500 kg * (12 m/s)^2
Kinetic Energy = 0.5 * 500 kg * 144 m^2/s^2
Kinetic Energy = 36,000 J
For the red car:
Kinetic Energy = 0.5 * 500 kg * (3 m/s)^2
Kinetic Energy = 0.5 * 500 kg * 9 m^2/s^2
Kinetic Energy = 2,250 J
Therefore, the blue car has the greatest kinetic energy of 225,000 joules.
