A steady, incompressible two-dimensional velocity field is given by the following components in the xy-plane
u = 0.205 + 1.72x + 0.851y
v = -0.509 + 0.953x - 1.72y
(a) Calculate the acceleration field (find expressions for the acceleration components ax and ay).
(b) Calculate the acceleration at the point (x,y) = (1,3).
