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) Responses The truck has more kinetic energy because it has a greater mass. The truck has more kinetic energy because it has a greater mass. The truck has less kinetic energy because it has greater mass. The truck has less kinetic energy because it has greater mass. The car has more kinetic energy because it moves fast down hills. The car has more kinetic energy because it moves fast down hills. The car and truck have the same kinetic energy. The car and truck have the same kinetic energy.

The correct response is: The truck has more kinetic energy because it has a greater mass.
Kinetic energy is calculated using the formula:
\[ KE = \frac{1}{2} mv^2 \]
where \( KE \) is the kinetic energy, \( m \) is the mass, and \( v \) is the velocity. Since both the truck and the small car are moving at the same speed, the difference in their kinetic energy comes from their mass. Since the truck has a greater mass, it will have more kinetic energy.
