Question

A runner is traveling around the track below at a constant speed. Is she accelerating?

A. Yes, she is accelerating because her speed is constant.


B. Yes, she is accelerating as she turns and changes direction.


C.No, she is not accelerating because there is not an incline to the track.


D.No, she is not accelerating because her speed is constant.

Answer 1

D.No, she is not accelerating because her speed is constant.

Step-by-step explanation:

The rate of change of velocity with respect to time is known as acceleration.

acceleration =change in velocity/time

As she is running at constant speed and there is no change in velocity so she is not accelerating.
