A car is traveling along the circular curve of radius r = 300 ft . At the instant shown, its angular rate of rotation is \dot { \theta } = 0.4 rad/s , which is increasing at the rate of \ddot { \theta } = 0.2 rad/{s}^{2} . Determine the magnitudes of the car’s velocity and acceleration at this instant.
