The kinetic energy (KE) of an object 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 two cars have equal mass, the kinetic energy will depend solely on their velocities. Therefore, if one car has a higher velocity than the other, it will have more kinetic energy. So to determine which car has more kinetic energy, you would need to compare their velocities. The car with the higher velocity will have greater kinetic energy.
