Which of the following is NOT accelerating? A ball being juggled.
A women walking at a constant speed of 2.5 m/s along a straight path.
A rocket taking off.
A car slowing down toward a stop sign.

Second Option

Explanation:

The answer is the second option or "a women walking at a constant speed of 2.5 m/s along a straight path." Remember that constant means always staying the same so if a women is walking at a constant speed of 2.5 miles per hour on a straight path, she will remain at her current speed at 2.5 mils per hour which isn't acceleration.

Hope this helps.
