A steady, two$-$dimensional velocity field is given by the following components in the xy$-$plane:

u$=1\mathrm{.}1+2\mathrm{.}8$x$+0\mathrm{.}65$y v$=0\mathrm{.}982\mathrm{.}1$x$2\mathrm{.}8$y $(1)$

Calculate the acceleration field $($find the expression for acceleration components ax and ay $),$ and calculate the

acceleration at the point $($x$,$y$)=(2,3).($Answers: ax $=9\mathrm{.}233,$ay $=14\mathrm{.}37)$
