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 and initial velocities with the average velocity?
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.
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 mathematical equation of the gas laws?

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.
When is acceleration equals half of the sum of initial and final velocities?
Acceleration is equal to half the sum of initial and final velocities at the midpoint of the motion when the acceleration is constant. This occurs when the object has undergone half of the acceleration time and traveled half of the distance between initial and final velocities.
How do you find final and initial velocities with the average velocity?
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.
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?
The final velocities of the gliders after a perfectly elastic collision will also be equal and opposite to their initial velocities. This is due to the conservation of momentum and kinetic energy in elastic collisions.
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.
What will be the acceleration of a car moving in a uniform acceleration?
The acceleration of a car moving with uniform acceleration will remain constant. This means that the rate of change of its velocity will be consistent over time, resulting in a steady increase or decrease in speed.
What is the change in velocity for each of the following initial and final velocities?
The change in velocity is the final velocity minus the initial velocity. For example, if the initial velocity is 10 m/s and the final velocity is 20 m/s, the change in velocity is 10 m/s.
What is a car's acceleration between 25 s and 30 s?
To find the acceleration between 25 s and 30 s, you would need to know the initial and final velocities during that time interval. Acceleration is calculated as the change in velocity over time. Once you have the velocities at 25 s and 30 s, you can use the formula: acceleration = (final velocity - initial velocity) / time.
How to get initial accelaraion?
To calculate initial acceleration, you need to determine the change in velocity over time. Initial acceleration can be calculated using the formula a = (v - u) / t, where a is the acceleration, v is the final velocity, u is the initial velocity, and t is the time taken. By plugging in the values for initial and final velocities, along with the time taken for the change, you can find the initial acceleration.
How do you find the minimum uniform acceleration with out time?
You need initial and final velocities (U,V) and distance (S), > acceleration = (V2 - U2) / (2 * S)
How is average velocity of a body calculated when its velocity changes at a non-uniform rate?
The average velocity of a body with non-uniform acceleration can be calculated by taking the average of the initial and final velocities over the time interval. This is done by adding the initial and final velocities and dividing by 2. Mathematically, the formula for average velocity is (v_initial + v_final) / 2.
is it correct that the average velocity is always equal to the mean value of initial and final velocities?
No, the average velocity is calculated as the total displacement divided by the total time taken to travel that distance. It is not simply the mean of the initial and final velocities.
The temperature has fallen from 1 degrees to -13 degrees how far has it fallen?
change = final - initial -13 - 1 = -14 It has fallen 14 degrees.
