    Vector Multiple Choice Question

    ABCD is a trapezium where AB = 2, DC = 3u and AD = v. M is the midpoint of DC. Vector BM expreseed in terms of u and v is equal to:

    A) v - \frac{3}{4}u

    B) v - \frac{3}{2}u

    C) -v + \frac{3}{2}u

    D) v - \frac{9}{4}u

    E)  -v - \frac{3}{4}



    I have also drawn a diagram for this, but unfortunately I cannot include it in this thread. I am completely useless when it comes to coputers!
