in, and 3 in from the boundary, assuming(a) a linear velocity distribution and (b) a parabolic velocity distribution. By referring to the figure and basic calculus prove that velocity can be written as v = 45 - 5(3 - y)^2 NOTE: The parabola in the sketch has its origin at B and its vertex at A (terminal velocity U=45 in/sec).
