Two identical cars are on a test track. Car A goes from rest to 25 m/s in 8 seconds. Car B goes from rest to 25 m/s in 6 seconds. Which car required more power to get to 25 m/s? How can you tell?

Step-by-step explanation:

Let mass of car be m.

Kinetic energy = 0.5mv²

Change in Kinetic energy for car A = 0.5 x m x 25²-0.5 x m x 0²=312.5 m

Change in Kinetic energy for car B = 0.5 x m x 25²-0.5 x m x 0²=312.5 m

Power is the ratio of energy to time.

The power required for car B is more compared to car A.
