Answer 1

Hi Intelligent...................●●●●●

Here is your answer....................◆◆◆◆◆

If we apply force and throw a ball upward then by the powerful force applied by a person will help the ball to go to only a certain height only.
Then after reaching at certain height , the ball will fell a loss in energy and it will start coming down at fast speed.

So,here I have given my view,hope this will help you

Answer 2

ANSWER:
The speed of the ball decreases with time,then at the highest point ,the vertical component of velocity becomes 0.
Then the body starts accelerating due to g and hits the ground with v =√(2gh).
Change in velocity is generally given by: v-u=gt.
