## Question:

The car travels along the circular curve having a radius r = 400 ft .At the instant shown, its angular rate of rotation is $\dot { \theta }$ = 0.025 rad/s , which is decreasing at the rate $\ddot { \theta }$ =-0.008 rad/${s}^{2}$ . Determine the radial and transverse components of the car’s velocity and acceleration at this instant and sketch these components on the curve.
