Question

A steady two-dimensional flow field is specified by the stream functionψ=kx3y,\psi = kx^3y,where xx and yy are in meter and the constant k=1 m−2 s−1k = 1 \text{ m}^{-2} \text{ s}^{-1}. The magnitude of acceleration at a point (x,y)=(1 m,1 m)(x, y) = (1 \text{ m}, 1 \text{ m}) is ________ m/s2\text{m/s}^2 (round off to 2 decimal places).
