Which of the following represents a case in which you are not accelerating? - Driving 60 miles per hour around a curve - Going from 0 to 60 miles per hour in 10 seconds - Slamming on the brakes to come to a stop at a stop sign - Driving in a straight line at 60 miles per hour

Driving in a straight line at 60 miles per hour

Explanation:

In the first case there's an acceleration that modifies the direction of the movement.

In the second case there's a lineal acceleration that increases the speed of the car.

in the third case there's a negative acceleration that reduces the speed of the car.

On the third case the speed is constant so the acceleration is 0 mi/s^2
