Can an object's average velocity equal zero when object's speed is greater than zero?
Yes, when the object moves in a straight line at a constant rate.
Yes, when the object returns to its original position.
No, it is impossible because they are always equal
No, it is impossible because the magnitude of the velocity is always greater than speed.

This graph show that
the object is throw upward
the object throw downward

This graph show that
the ball decelerates and then accelerates after bounces off the floor
the ball decelerates and then accelerates after bounces off the wall
The ball stays at rest at the left of the origin, then switches position and continues to stay at rest at the right of the origin.
The ball moves to the left with constant velocity toward the wall and then bounces off the wall with constant velocity.
