## Question:

A radar gun at rotates with the angular velocity of $\dot { \theta }$ = 0.1 rad/s and angular acceleration of $\ddot { \theta }$ = 0.025 rad/${s}^{2}$ , at the instant $\theta$ =45° , as it follows the motion of the car traveling along the circular road having a radius of r = 200 m. Determine the magnitudes of velocity and acceleration of the car at this instant.
