A fluid flow is defined by $u=(0\mathrm{.}4x^2+2t)\frac{m}{s}$ and $v=(0\mathrm{.}8x+2y)\frac{m}{s},$ where $x$

and $y$ are in meters and $t$ is in seconds.

Determine the magnitude of the velocity of a partiole passing through point $x=3\mathrm{.}2m.y=1m$ if it arrives when $t=3s.$

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

$V=$

Part B

Determine the direction of the velooity of a particle passing through point $x=3\mathrm{.}2m,y=1m$ if it arrives when $t=3s.$ Enter your answer as the angle $v,$ which the veiocity makes with the $x$ axis.

measured counterciockwise from the positive $x$ axis.

Express your answer using three significant figures.

${}_v=$

Part C

Determine the magnitude of the acoeleration of a paricle passing through point $x=3\mathrm{.}2m,y=1m$ if it arrives when $t=3s$

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