The car that has more kinetic energy is the car with the greatest speed.
Kinetic energy (KE) is calculated using the formula:
\[ KE = \frac{1}{2} mv^2 \]
where \( m \) is the mass of the object and \( v \) is its speed. Since both cars have equal mass, the one with the greater speed will have a higher kinetic energy due to the \( v^2 \) term in the formula.
