The speedometer of a car indicates a constant speed of 30 miles per hour. From this we can say that the acceleration of the car is

1) zero. 2) nonzero. 3) can't really say. This is because 4) no net force is acting on the car. 5) any reading (other than zero) on the speedometer indicates acceleration. 6) the car may be changing its direction.
