Anyone can contribute an answer, even non-tutors.
How todo (ii)? Thank you.
Find what is t first.
To find acceleration, differentiate the expression. Then sub the value of t in
To find displacement, integrate the expression. Upper bound is the value of t you find above, lower bound is 0
See 1 Answer
In this chapter, we need to realise that differentiating displacement gives velocity and differentiating velocity gives acceleration. The reverse processes are integration.
We also need to be able to distinguish between displacement and distance, as there is a difference between the two terms. If you are taking Physics as well, you would probably have learnt the difference between these two terms.
