Hi Emma,

so firstly we would need to establish that this graph is a maximum point graph.

a). after we find the solution for t @ maximum point using differentiation, we would just subsitute it inside the quation and realise maximum point is below 2.5

b) find the t in terms of a. using differentiation and then substitute it inside the original equation 1 to solve for a:).
hope this helps, just ask if anything is unclear or wrg:)
