    Alright all im doing some mechanics and im not allowed to work in suvat form (ie the simple way), and ive been told to use vectors only!

    So i need to be able to use the

    V^2 = u^2 + 2ab formula, but i need this in vectors terms, and how do i deduce/derive it?

    Ive tried googling it, and even manipulating vectors for distance etc. to reach it, but still no luck.

    Help will be appricated .

    What do you mean by "use vectors only"? It is not clear to me what kind of result you wish to obtain.

    As in im not allowed to use equations without proving them. (SUVAT).
    But as im only allowed to work in vectors, but can the SUVAT equations be put into vector form?

    v^2 = v_0^2 + 2a\Delta s \, - Thats the equation i want, but how do i deduce it?
