urgent, need fluids help

    hi need help with a past paper question in fluids, if anyone can do it I would really appreciate it!

    the velocity distribution for the flow of a newtonian fluid between two wide, parallel plates is given by the equation
    3v (y)^2
    u= 2 [1-(h) ] in words u equals 3v divided by 2 all multiplied by 1 minus y over h squared.

    where v is the mean velocity.
    the fluid has a viscosity of 1.915 Ns/m^2. when V=0.61m/s and h = 5mm, determine
    (A) the shearing stress on the bottom wall.
    (B) the shearing stress acting on the plane parallel to the wall.
    (C) the shearing stress at midplane, i.e. at centreline.

    thanks for looking
