Final answer:
The average velocity of a ball dropped from a certain height can be calculated by dividing the total displacement by the total time taken. In this case, the average velocity is given by h/t, where h is the height and t is the time taken to reach the ground. The units of average velocity are meters per second (m/s).
Step-by-step explanation:
The average velocity of a ball dropped from a certain height can be calculated by dividing the total displacement by the total time taken. In this case, since the ball is dropped vertically, the displacement is equal to the height from which it is dropped. Let's say the height is represented by 'h'. So, the average velocity is given by:
average velocity = displacement / time = h / t
Where 't' is the time taken for the ball to reach the ground. Therefore, the average velocity is h / t which has the units of meters per second (m/s).
