## Examples
> Sally aggressively drives her Alfa Romeo from rest to 50 m/s in 6s. What is her acceleration?
1. Start:
- $v_0 = 0 m/s$
- $t_0 = 0s$
- $x_0 = 0m$
2. Final:
- $v = 50 m/s$
- $t = 6s$
- $x = ?$
3. Using the equation $v = v_0 + at \to a = \frac{(v - v_0)}{t}$, $a$ = $(50 m/s - 0 m/s)/ 6s = 8.3m/s^2$
4. Assess: do the units make sense? Is the answer reasonable?
