Expert Answer

Step 1

Average acceleration is given as

Physics homework question answer, step 1, image 1

Step 2

To determine the direction of change in velocity, we subtract v2-v1 geometrically.

Physics homework question answer, step 2, image 1

The average velocity is hence towards the center.
