If two cars have the same mass but different speeds, the faster car has

Explanation:
Kinetic energy depends on motion, specifically KE = 1/2 m v^2. With the same mass, KE scales with the square of speed, so increasing speed increases energy by a factor of the square of the speed ratio. If one car is faster, its velocity term is larger, and because that velocity is squared, its kinetic energy is larger. For example, doubling the speed makes KE four times larger when mass stays the same. Height doesn’t affect kinetic energy in this context, since it’s about motion along a path, not potential energy from height. Therefore, the faster car has greater kinetic energy.
