The formula we use to calculate acceleration is: v-u/t. Which is the ending speed taken away by the original speed all divided by the duration of the acceleration.

So if we substitute the numbers in, it will look like this: (7-0)/3 which gives you 2.33m/s^2

We know, a = Δv / t
Here, Δv = 7 m/s
t = 3 s

Substitute their values, 
a = 7 / 3 
a = 2.33 m/s²

So, your final answer is 2.33 m/s²

Hope this helps!
