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