A race car, starting from rest, travels around a circular turn of radius 28.5 m. At a certain instant, the car is still accelerating, and its angular speed-is 0.794 rad/s. At this time, the total acceleration (centripetal plus tangential) makes an angle of 35.0° with respect to the radius. What is the magnitude of the total acceleration?
