Kinetic energy (\(KE\)) is given by the formula:
\[
KE = \frac{1}{2}mv^2
\]
where \(m\) is the mass of the object and \(v\) is its velocity.
If a bus and a car are traveling at the same speed, their kinetic energies will depend on their masses. Typically, a bus has a much greater mass than a car. Since kinetic energy is directly proportional to mass, the bus will have a higher kinetic energy than the car if they are traveling at the same speed.
In summary, since the bus has a larger mass compared to the car, it will have a higher kinetic energy at the same speed.
