As it usually goes let's see if we can regurgitate the questions and get someone who can actually do the subject to answer them properly for us.

1) To win a 400m race, the runner needs:
- biggest initial velocity?
- biggest acceleration?
- biggest average velocity?
- ??

unknown) Discuss why Graphene might not be suitable for all applications in spite of its high breaking stress (compared to Steel)

unknown) I got Cornstarch for the viscosity

1) highest average velocity

unknown 1) it has high strength only along a single axis. Also it's material properties for thermal and electrical conduction are completely different. There are so so so many reasons. Not sure what they'd want for A-level tbh...

unknown 2) what's the question?
