A radar gun at O

rotates with the angular velocity of $\backslash$theta $$

$=0\mathrm{.}1$ rad$/$s

and angular acceleration of $\backslash$theta $$

$=0\mathrm{.}045$ rad$/$s$2$

$,$ at the instant $\backslash$theta

$=45$

$,$ as it follows the motion of the car traveling along the circular road having a radius of r

$=220$ m

$.$ Determine the magnitudes of velocity of the car at this instant. Determine the magnitude of acceleration of the car at this instant.
