From the question we come to know several important information's and based on them we can reach the desired result.
Initial speed = 0 m/s
Final speed = 10 m/s
Initial time = 0 sec
Final time = 4 sec
Then
Average acceleration = (Final speed - Initial speed)/(Final time - Initial time)
= (10 - 0)/(4 - 0)
= 10/4
= 2.5 m/s^2
So the average acceleration is 2.5 m/s^2. I hope this has made it clear to you about the procedure of solving such problems.
Can you provide anymore information or was that the whole question?
The correct answer is The page number only
Since you've already mentioned who the author is, you don't have to mention him again. The book title would only be added if you're using multiple sources from the same author. If only one, then the page number only.
