    if a is proportional does that means a=k(t+to)^-3

    and hopefully the constant cancels?

    I follow that through and get v and then intergrate to get x but unsure about the constant from x?

    + i'm unsure about the question..

    Any solutions would be great! Thanks!



    That's the question from the edexcel M3 book Thanks !

    Yes.

    Doesn't matter, it's a definite integral between "t" and "0" since you're interested in how far it's travelled

    + i'm unsure about the question..
    Just follow your nose, or ask on the bits what you're unsure about.

    Any solutions would be great! Thanks!
    It does work out. I'm not going to do a solution for you. If you want to post any intermediate results, or have as specific place where you're stuck....
