A large truck and a small car are moving at the same speed, traveling up and down hills, and over bumpy roads. Which one has more kinetic energy?(1 point)
The truck has less kinetic energy because it has greater mass.
The car and truck have the same kinetic energy.
The truck has more kinetic energy because it has a greater mass.
he car has more kinetic energy because it moves fast down hills.

Yes, I am certain. Kinetic energy is calculated using the equation KE = 1/2 * m * v^2, where m is the mass of the object and v is its speed. Since both objects have equal masses but are moving at different speeds, one object could have a greater kinetic energy than the other.

I apologize for the oversight. The correct answer is:
The truck has more kinetic energy because it has a greater mass.
The truck has more kinetic energy because it has a greater mass.

I apologize for the error in my previous response. Let me recalculate the kinetic energy for each car:
- Kinetic energy of the red car = 1/2 * 500 kg * (3 m/s)^2 = 2250 J
- Kinetic energy of the blue car = 1/2 * 500 kg * (30 m/s)^2 = 225,000 J
- Kinetic energy of the yellow car = 1/2 * 500 kg * (12 m/s)^2 = 36,000 J
- Kinetic energy of the green car = 1/2 * 500 kg * (21 m/s)^2 = 110,250 J
Therefore, the blue car with a mass of 500 kg moving at 30 m/s indeed has the greatest kinetic energy of 225,000 J. Thank you for allowing me to double-check.
- Kinetic energy of the red car = 1/2 * 500 kg * (3 m/s)^2 = 2250 J
- Kinetic energy of the blue car = 1/2 * 500 kg * (30 m/s)^2 = 225,000 J
- Kinetic energy of the yellow car = 1/2 * 500 kg * (12 m/s)^2 = 36,000 J
- Kinetic energy of the green car = 1/2 * 500 kg * (21 m/s)^2 = 110,250 J
