Answer:

A) Car B has more energy than Car A

Step-by-step explanation:

The kinetic energy of a car is given by:


K=(1)/(2)mv^2

where

m is the mass of the car

v is its speed.

In this problem, we know that:

- The speed of car B is greater than the speed of car A

- We assume that the mass of the two cars is the same

Therefore, since the kinetic energy is proportional to the square of the speed, this means that car B has greater kinetic energy than car A.
