Let's take a simple example to illustrate the concept.
A pitch is thrown by a pitcher. It starts at zero velocity (in his hand) and reaches a final velocity of 100 mph. Average velocity will be (100 + 0)/2 = 50 mph
Obviously the maximum velocity is 50 X 2 = 100 mph
However this is only true if the initial velocity (or the final velocity for a ball slowing down) is zero.

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.
A motorcycle accelerates from 15 ms to 20 ms over a distance of 50 meters. What is its average acceleration?
1.75 m/s^2
If the velocity of an object is tripled its kinetic energy is multiplied by?
When the velocity of an object is tripled, its kinetic energy is multiplied by 9. This is because kinetic energy is proportional to the square of the velocity (KE = 1/2 * m * v^2), so when the velocity is tripled, the kinetic energy is calculated as (3v)^2 = 9 * v^2.
What is the braking time from 1.5 to 2 seconds what is the final velocity?
To calculate the braking time from 1.5 to 2 seconds, we need to know the initial velocity and the acceleration of the object. The final velocity can be determined using the formula: final velocity = initial velocity + (acceleration * time). If we have this information, we can plug in the values to find the final velocity at 2 seconds.
What is the expression for average acceleration?
Acceleration = Change in velocity divided by the change in time. This formula only works if velocity is constant. If velocity is not constant, find the acceleration for both points in time. Then add the two accelerations and divide by 2.

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)
How do you find displacement when you only have acceleration initial velocity and final velocity?
You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
The rate of the velocity of an object?
To calculate the velocity of an object you can use the formula v=d/t. v=velocity, d=distance, and t=time. You can also calculate velocity using a=change in v/change in t, v(final)=v(initial)+at, v(average)=v(final)+v(initial)/2, or v(final)^2=v(initial)^2+2ad, or p=mv.
What are a few physics formulas for finding time?
Change in Distace= Initial velocity multiplied by change in time plus half the accleration times change in time squared x=VoT+.5aT^2 Final velocity squared=Intial velocity squared plues two times accleration times change in distance Vf^2=Vo^2+2aX Final velocity= Initial velocity plus accleration times change in time Vf=Vo+aT
How do you calculate acceleration from velocity?
There are 3 formula 1. Final velocity = starting velocity + (acceleration)(time) 2. Final velocity^2 = starting velocity^2 + 2(acceleration)(distance) 3. Distance = (starting velocity)(time) + 1/2(acceleration)(time^2) Use whichever you can use.

Average velocity always equals one-half the sum of the initial and final velocities?
Is this a question? or a statement that you are unsure of? Well anyways, this would be correct if acceleration was a constant but if acceleration is not a constant, the (not-constant) acceleration would change the rate of velocity and thus that statement/question would be false.
What is initial velocity if its less than final velocity?
i think it's 2
How do you find final velocity given height and mass?
the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5
