A car is speeding up uniformly at a rate of 0.600 m/s2 while traveling counterclockwise around a circular track of radius 495 m. At the instant the car is moving due north, its speed is 8.00 m/s. What is the magnitude and direction of the total acceleration of the car at this instant? Use a positive angle for west of north and a negative angle for east of north.
