You can't.
You only know what half the sum of (initial + final) is, (it's the average), but you don't know what the initial and final are.

When are final and initial velocities taken ball kicked at 30 degrees at 10ms?
Initial velocity is 10 m/s in the direction it was kicked. Final velocity is 0, when friction and air resistance finally causes it to come to a halt.
How do you find final velocity given mass of both objects and there initial velocities and one of their final velocities?
Suppose the two masses are m1 and m2. Their initial velocities are u1 and u2 and final velocities are v1 and v2. Then, using conservation of momentum. m1*u1 + m2*u2 = m1*v1 + m2*v2 Both m1 and m2 are given. Their initial velocities u1 and u2 are given and one of the two final velocities v1 and v2 is given which leaves only one unknown. So substitute all those values and calculate away.
Can the effect of initial velocity on final velocity be predicted?
Well, (final velocity) = (initial velocity) + (acceleration x time)
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.
What is the acceleration in science if you know average speed and time?
If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.
When is acceleration equals half of the sum of initial and final velocities?
If you have a particle with constant acceleration, and you add the initial and final velocities and then divide them by two, what you get is the average velocity of the particle in that period of time.
If two gliders of equal mass and equal and opposite initial velocity collide perfectly elastically what are the final velocities of the gliders in terms of the initial velocities?
Both the gliders will be travelling at exactly the same speed as the initial velocity but in opposite directions.
What is the change in velocity for each of the following initial and final velocities?
We don't answer questions taken from copyrighted materials.
is it correct that the average velocity is always equal to the mean value of initial and final velocities?
It is correct only if the object in question is subject to a constant acceleration.
When are final and initial velocities taken ball kicked at 30 degrees at 10ms?
Initial velocity is 10 m/s in the direction it was kicked. Final velocity is 0, when friction and air resistance finally causes it to come to a halt.

Is acceleration equal to initial velocity minus the final velocity divided by the time?
No, It is the average velocity.
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 :)

What is the Formula in Final Velocity?
Final velocity = (Initial velocity) + (time)(acceleration)
How do you find the time given only the distance and the initial and final velocity?
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
