Children are bouncing rubber balls One child drops a ball At the same time the second child throws a ball downward with an initial speed of 10ms What is the acceleration of each ball in motion?

Exactly the same as each other.

An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.
How to get initial accelaraion?
To get the initial acceleration, you need to divide the force by the mass.
What would be true of the values for initial velocity and final velocity if the acceleration were zero?
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.
To find acceleration you subtract what?
To find acceleration you subtract initial velocity from final velocity and divide it by time.
The equation used to find acceleration is what?
Average acceleration = final velocity - initial velocity/ final time - initial timeOr for short:Aave=Vf-Vi/Tf-TiHope that helps :)

Does uniform speed properly characterize the motion of a heavy object thrown violently downward from a tall building?
No. Regardless of its initial speed, the object still experiences downward acceleration at the rate of 'G'.
How do you find initial acceleration.?
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.

How do you calculate an objects acceleration?
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
How do geometric sequences apply to a bouncing ball?
The ball does not return to its initial height after bouncing. So the height it reaches after the first bounce will be a fraction of the initial height, etc. This is a geometric sequence with common ratio 5/8.
What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
If you throw an object towards the ground would it acceleration be greater or less thatn an object free falling?
Both objects would eventually reach terminal velocity which means they would both fall at the same speed.- But - compared to the falling object, the downward acceleration of a thrown object is the same.
How do you find the initial velocity just with the accelaration final velocity and time?
To find acceleration, you take Vi [Initial Velocity] and you subtract if from Vf [Final Velocity.] (Vi - Vf) If they Vi and Vf are already given, you take the two givens and you subtract them from each other. Vi minus Vf. Do not do Vf minus Vi or it will be wrong. After you do that, you divide your answer from T [Time] (Vi - Vf) a= _____ t Once you get your answer, that will be your acceleration.
What would be true if the values for initial velocity and final velocity if the acceleration were zero?
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.

When an object's final velocity is less than its initial velocity it has what kind of acceleration?
Negative acceleration.
