We know, a = (v₂-v₁) / (t₂-t₁)
Here, v₂-v₁ = 19 m/s
t₂-t₁ = 2 s

Substitute it into expression, 
a = 19/2
a = 9.5 m/s²

So, your final answer is 9.5 m/s²

Hope this helps!

I would say that strong language typically reveals strong feelings: strong language would reveal desperation, or very strong feelings: weak feelings would not demand it, and would be more likely accompanied by more controlled behavior.
