Question

#18 Two cars travel around the same curve, one at twice the speed of the other. After traveling the same distance, which car, if either, has experienced the larger change in velocity? Explain. a) The car with the slower speed experiences the larger change in velocity because it is taking the curve in a greater interval of time. b) Neither car experiences a larger change in velocity because they travel the same curve in the same amount of time. c) The car with the higher speed experiences the larger change in velocity because it is taking the curve in a shorter interval of time.

Explanation / Answer

The car with the higher speed experiences the larger change in velocity because it is taking the curve in a shorter interval of time.
