A fluid flow is defined by $u=(6x^2-3y^2)\frac{m}{s}$

and $v=(4xy+y)\frac{m}{s},$ where $x$ and $y$ are in

meters.

Determine the magnitude of the velocity of a particle at point $(2\mathrm{.}5m,2m).$

Express your answer to three significant figures and include the appropriate units.

$V=$

Part B

Determine the magnitude of the acceleration of a particle at point $(2\mathrm{.}5m,2m).$

Express your answer to three significant figures and include the appropriate units.

$a=,\frac{m}{s^2}$
