Please explain straight line motion question ?
A tennis ball with a velocity of +10.0 m/s to the right is thrown perpendicular at a wall. After striking the wall, the ball rebounds in the opposite direction with a velocity of -8.0 m/s to the left. If the ball is in contact with the wall for 0.012s, what is the average acceleration of the ball while it is in contact with the wall ?
This is High School Physics question from straight line motion under constant acceleration chapter.
Please explain the question. Person standing in front of wall throws the ball towards the ball at +10.0 m/s. The ball hits the wall and rebounds toward the person at -8.0 m/s. Did I understand the problem correctly ?

You know the velocity before and after the collision, you know the time it took to make that change in velocity.
Do you know the equation for average acceleration ?
If so write it. If not I can give it to you.
You know everything in that equation.
