The acceleration is defined as the ratio between the change in velocity and the time elapsed to perform such a change.
These "changes" are indicated with the capital greek letter delta,
, and when you write
you mean the difference between the finial and the inital values of the variable x:
![\Delta x = x_{\text{fin}} - x_{\text{init}}](https://tex.z-dn.net/?f=%20%5CDelta%20x%20%3D%20x_%7B%5Ctext%7Bfin%7D%7D%20-%20x_%7B%5Ctext%7Binit%7D%7D)
So, the acceleration is defined as
![a = \dfrac{\Delta v}{\Delta t} = \dfrac{v_{\text{fin}} - v_{\text{init}}}{t_{\text{fin}} - t_{\text{init}}}](https://tex.z-dn.net/?f=%20a%20%3D%20%5Cdfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D%20%3D%20%5Cdfrac%7Bv_%7B%5Ctext%7Bfin%7D%7D%20-%20v_%7B%5Ctext%7Binit%7D%7D%7D%7Bt_%7B%5Ctext%7Bfin%7D%7D%20-%20t_%7B%5Ctext%7Binit%7D%7D%7D)
In this case, the initial velocity is 35, the final velocity is 65. Assuming we start the clock at the beginning of the observation, the inital time is 0 and the final time is 5. So, we have
m/s^2
Answer:
not sure which is the origional-
if the big one is the origiinal, then 1/2
if the small one is the origional- then 2-1
