P6 A car travels around a circular track at constant speed, as shown. It is observed that the car takes 15.71 seconds to go from point A to point B along the track (exactly a quarter circle). An accelerometer mounted on the car shows that its acceleration has a constant magnitude of 7.0 m/s2. Please answer each of the following questions. For answers that require vectors, refer to the instant shown in the figure. a) What is the radius of...
