    So if the vertical length from x to y is 25 m, then the gpe lost from x to y would be 25*9.81*mass of motorcyclist?
    Yep, mass was 190kg, giving 4.66 x10^4 J

    No - non-uniform could mean decreasing acceleration which is wrong

    Depends on the mark scheme this year. Because of the situation, I don't think they'd accept that, as it's not specific enough. That is just 100% speculation though

    thanks a lot! 2 questions, is surface area ok as a component of drag, and is deceleration ok instead of negative acceleration?

    Strictly speaking surface area is wrong - but might be Ok on mark scheme.
    Deceleration will be OK.

    For 4e i thought as the cyclist leant over the bike his centre of mass moves further away from y so the moment increases and hence x increases?

    Is there a potential answer that the force from the driver on the airbag would've caused the airbag to burst, rather than him rebounding?
