To determine which statement is true, we need to understand the concept of kinetic energy. Kinetic energy (KE) is given by the formula:
\[ KE = \frac{1}{2} mv^2 \]
where:
- \( m \) is the mass of the object,
- \( v \) is the speed of the object.
In this scenario, both the small car and the large bus are traveling at the same speed of 60 mph. However, the mass of the bus is greater than the mass of the car. Therefore, even though they are traveling at the same speed, the bus, having a larger mass, will have more kinetic energy.
Thus, the correct answer is:
**The bus has more kinetic energy than the car.**
