Answer:
A) Car B has more energy than Car A
Explanation:
The kinetic energy of a car is given by:
[tex]K=\frac{1}{2}mv^2[/tex]
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.
