Question

mrs.wilson is driving her car to the store. she drives on a street where the speed limit is 50 mph. then she turns into a street.where the speed limit is 45 mph. what happens to the kinetic energy of her car?

Answer 1

Since kinetic energy is directly proportional to the square of velocity, a decrease in velocity will result in a decrease in kinetic energy. Therefore, when Mrs. Wilson turns into the street with a speed limit of 45mph (which is lower than the previous speed limit of 50mph), the kinetic energy of her car will decrease.
