We use the following formula to determine our acceleration:
[tex] acceleration = \frac{(final velocity) - (initial velocity)}{time} = \frac{change of velocity}{time} [/tex]
We normally use letters in this formula, which gives us:
[tex]a = \frac{v}{t} [/tex]
Filling in this formula gives us:
Δv (change of velocity) = 12 - 4 = 8 m/s
t = 1s
[tex]a = \frac{8}{1} = 8 m/s^2[/tex]
So our answer: the acceleration is [tex]8m/ s^{2} [/tex]
