Answer:
[tex]a=\frac{v_{f}-v_{i}}{t_{f}-t_{i}}[/tex]
Explanation:
Formula for AVERAGE acceleration
[tex]a=\frac{v_{f}-v_{i}}{t_{f}-t_{i}}[/tex]
[tex]v_{f}[/tex] is Final Velocity
[tex]v_{i}[/tex] is Initial Velocity
[tex]t_{f}[/tex] is Final Time
[tex]t_{i}[/tex] is Initial Time
Most of the time, the initial time will be 0, so you won't have to subtract.
