A large truck and a small car are moving at the same speed, traveling up and down hills, and over bumpy roads.

The truck has more kinetic energy because it has a greater mass.
The truck has more kinetic energy because it has a greater mass.
To determine which vehicle has more kinetic energy, we need to understand what factors affect kinetic energy. The formula for kinetic energy is KE = 1/2 mv^2, where KE represents kinetic energy, m represents mass, and v represents velocity.
In this scenario, the question states that the truck and car are moving at the same speed. Since speed is a component of velocity, we can assume that the velocity of both vehicles is the same.
However, the question does not provide any information about the mass of the truck and car. According to the formula, mass directly affects the kinetic energy. The larger the mass, the greater the kinetic energy, assuming the velocity remains constant.
Therefore, the correct answer is: "The truck has more kinetic energy because it has a greater mass."
To confirm this answer, we would need to know the exact mass of both the truck and the car.
