    ya it didnt ask for unit vector this is just method for finding out the vector in direction of ab with mag 28(4 times mag of ab(7))

    Maths P1 2011

    simple answer... unit vector of AB is VectorAB / 7(magnitude of vectoy)... multiply the resulting vector by 28 (magn given)... tat is the answer.. so basically all we are doin is multiplyin vector AB by 4 (28/7)
