Problem $3\mathrm{.}35$

Part A

A velocity teld for oil is defined by $u=(3y)\frac{m}{s},$

$v=(0\mathrm{.}6l^2+2)\frac{m}{s},$ where $t$ is in seconds and

$y$ is in meters.

If a particle is at the origin when $t=0,$ determine its position when

$t=6\mathrm{.}5s.$

Express your answers using three significant figures separated by a

comma.
