If a tennis ball is dropped from a height of 9 meters above the earth how long will it take to hit the ground?

neglecting air resistance, the distance (s) = 1/2 gravity acceleration(g) x time (t) squared; s =1/2 gt^2;solve for time using g = 9.81 m/s/s and you get t = 1.35 seconds

When a tennis ball is dropped to the ground it does not bounce back to its original height?
This is because...when a ball is dropped onto the ground, some of its energy and momentom is lost due to friction from the surface and when it bounces back....the gravitaton force pulls it downwards.... so it does not bounce back to its original height.if the ball is dropped onto an arena where there is zero gravitaion and friction, it will keep on bouncing back to thr same height.Aakash Dangaakash.dang@gmail.comB.tech - IT (3rd Year).
What is the order of the items to land if you dropped a brick a tennis ball and a maple leaf at the same time and at the same height?
The brick and the tennis ball might land at the same time, but the leaf will fall last.
How does the height from which a ball is dropped affect it's bounce?
h=(mgH-x)/mgm is massg is acceleration due to gravityH is height from which it is droppedh is height to which it returnsx is the energy lost due to collission with floor(probably dependant on the coefficient of restitution)well an object falls at 9.6 meters a second so every thing falls at the same time no matter what the height is but the bounce depends on what its made of.Serena Williams (USA)Real answer: Because of gravity. The higher you drop a ball, the more force acts upon it, pulling it towards the ground. After hitting an object, an equal and opposite force acts upon the tennis ball, repelling it. This is known as Newton's 3rd law.
How does the height of the release point affect the height of a tennis ball's rebound?
(Potential) energy is directly proportional to the release height.
Will a dropped ball or thrown ball hit the ground at the same time how and why?
if u let them go at the same time, both would hit at the same time, but if u throw them with say ur arms, the bowling ball because it goes less distance, the bowling ball will fall after about 2 feet, but the golf ball will sail a while WRONG In a vacuum, where there is a lack of air resistance, they should hit the ground at the same time. Based on the question, the bowling ball will hit the ground first.
A tennis ball is dropped from 1.55 m above the ground It rebounds to a height of 0.824 mWith what velocity does it hit the ground?
31 m/s
In an investigation:You drop a tennis ball from three different heights: 1 meter, 2 meters, and 3 meters above the ground. You measure to see how high the ball bounces.What is an independent variable?
The weight and the height because the gravity is constant.
If you drop a tennis ball how long will it take to touch the ground?
It depends on what height you drop it from.
While standing on the roof of a building, a child tosses a tennis ball with an initial speed of 15 m/s at an angle of 35° below the horizontal. The ball lands on the ground 2.6 s later. How tall, in meters, is the building?
The height of the building is 57.3 meters.
What is rebounce height of dropped tennis ball?
When you drop a ball from, say, 3 metres, it will bounce back to roughly 2 metres.
What is a good sentence with the word racket in it?
While me and my friend were playing tennis, he broke his racket, because he dropped it on the ground when he swung.

Does the rebound height has a constant relationship with the original height of a tennis ball when released from rest and bounces on a bench?
As long as the tennis ball is not thrust downward, yes, the tennis ball will bounce back to the same proportion of its original height, no matter how far it's dropped, as long as the height is small enough that air resistance can be ignored. The ball will eventually come to rest due to this air resistance.
What is the order of the items to land if you dropped a brick a tennis ball and a maple leaf at the same time and at the same height?
The brick and the tennis ball might land at the same time, but the leaf will fall last.
When you drop a tennis ball to the ground why doesnt it return to its initial height?
because it wants to be low enough to give a blowy
What is the law on action and reaction?
actions are what you do, reactions are what happens according to the action. for example; a tennis ball being dropped on the ground; the tennis ball dropping ( action ) the ball hitting the ground and bouncing back up ( reaction )
What is something that can be measured in meters?
Height of a human, width of a room/object, length of a tennis court, length of a car, length of a bridge, length of a race and height of a building, among other things.
