Explanation Given: The time taken by the ball during its entire flight is T . The maximum height attained by the ball is H . Formula Used: Write the expression for the average speed of the ball during the motion. v avg = D 1 t 1 ..... (1) Here, v avg is the average speed of the ball, D 1 is the distance covered by the ball in first half and t 1 is the time taken by the ball. The displacement of the ball in the second half is in the downward direction. Therefore, the displacement of the ball is − H . Write the expression for the average velocity of the ball in the second half of its motion. v → avg = D 2 t 2 ..... (2) Here, v → avg is the average velocity of the ball, D 2 is the distance covered by the ball in second half and t 2 is the time taken by the ball. Calculation: The average speed of a body during the first half of its entire motion to the maximum height is the ratio of the total distance covered by the ball to the time taken by the ball
