Answer:

[tex]a = 9.84 m/s^2[/tex]

Step-by-step explanation:

Given:

Initial speed (Vi) = 30 mi/h = 67.1 m/s

Final speed (Vf) = 52 mi/h  = 116.32

Time period(t) = 5 seconds

We know the formula of acceleration in terms of initial speed, final speed and time:

[tex]a = \frac{Vf -Vi}{t}[/tex]

[tex]a = \frac{116.32-67.10}{5}[/tex]

[tex]a = 9.84 m/s^2[/tex]
