A car travels in a flat circle of radius R. At a certain instant the velocity of the car is 24 m/s west, and the total acceleration of the car is 2.5m/s^2 53 degrees north of west. Find the radial and tangential components of the acceleration of the car at that moment. If the car's tangential acceleration is constant, how long will it take for it to make a one full circle from the point at which its velocity is 24m/s west?
