Two cars in motion have equal mass. Which car has more kinetic energy?
the car with the greatest size
the car with the greatest volume
the car with the greatest acceleration
the car with the greatest speed
The car with the greatest speed has more kinetic energy. Kinetic energy is given by the formula KE = (1/2)mv^2, where m is the mass of the object and v is its velocity (speed). Since the mass is equal for both cars, the kinetic energy depends solely on the speed.

So is it the car with the greatest speed?
Apologies for the confusion in my previous response. Yes, you are correct. The car with the greatest speed will have more kinetic energy.
The car with the greatest speed has more kinetic energy.
Kinetic energy depends on the mass and the square of the velocity of an object. In this case, the two cars have equal mass. Therefore, the car that is moving at a higher speed will have more kinetic energy, as the kinetic energy is directly proportional to the square of the velocity.
