Final problem, need help!!!! A race car, starting from rest, travels around a circular turn of radius 24.5 m. At a certain instant, the car is still accelerating, and its angular speed is 0.521 rad/s. At this time, the total acceleration (centripetal plus tangential) makes an angle of 35.0° with respect to the radius. (The situation is similar to that in Figure 8.15b.) What is the magnitude of the total acceleration? I don't know where to start!!!
