this is what I got up to so far..whats u?

u is velocity; function of y

U is maximum velocity (at the top)

so.. do i leave my answer as 40 s^-1 * u ?

plug in dynamic* viscoity

wat? i dont get it

not sure what u mean... can i leave my answer like tat?

shear is (mu) * ( derivative of velocity profile with respect to the height)

take the derivative, plug in mu (dynamic viscosity) , plug in the height you want it for, you get your needed answer
you don't know mu? look it up

big U is given constant
u= velocity profile
