When A child throws a ball up in the air to a height of 3.5 m and catches it at the same point from which he threw it. The ball is in the air for a total of 1.7 seconds. What is the average velocity?
The average velocity of the ball is 0 m/s because it returns to its original position after 1.7 seconds. Since the displacement is zero, the average velocity is also zero.
