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.
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.
1.75 m/s^2
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.
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.
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.

Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
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.
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.
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
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.

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.
i think it's 2
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
