A ball of mass 81 kg is dropped from a height of 22 m. What is the height at which the velocity is exactly half of the final velocity with which it hits the ground?
Hi,
Hope you are doing well.
We know that, Final velocity of the ball is given by,
Where,
is acceleration due to gravity,
is height at which the ball is dropped,
Let be the height at which the velocity is exactly half of the final velocity with which it hits the ground,
We have,
Squaring both sides, we get,
Hope this helped for your studies. Keep learning. Have a good day.
Feel free to clear any doubts at the comment section.
Please don't forget to give a thumbs
up.
Thank you. :)

A 0.2 Kg ball is dropped with no initial velocity from a height of 6 m. It drops vertically with no air drag, it hits the flat, concrete ground and re-bounces upward in a vertical direction reaching a maximum height of 4 m. (i) Calculate the speed of the ball when it hit the ground. (ii) Calculate the speed of the ball when it began moving upward. (iii) Calculate the magnitude of the impulse provided by the ground to the...
