The auto in the sketch moves forward as the brakes are applied. A bystander says that during the interval of braking, the auto’s velocity and acceleration are in opposite directions. Do you agree or disagree?
Why acceleration at any instant do not velocity at any instant?
If a car is moving at 50mph and it rounds a corner, also at 50mph, does it maintain a constant speed? A constant velocity? Defend your answer.
