1a. A car drives around a circular track of diameter 154 m at a constant speed of 45.1 m/s. During the time it takes the car to travel 97 degrees around, what is the magnitude of the car s average acceleration? b. A car starts from rest, then accelerates at a constant rate over a distance of 63 m. It then immediately decelerates at a constant rate over a distance of 122 m. The entire trip lasts a total duration...
