A racing car, starting from rest, travels around a circular turn of radius 28.9 m. At a certain instant, the car is still accelerating, and its angular speed is 0.421 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?
