A car starts from rest and drives around a circular track with a radius of 45.0 m at constant tangential acceleration. If the car takes 27.0 s in its first lap around the track, (a) what is the magnitude of its overall acceleration at the end of that lap? (b) What angle does the acceleration vector make with a radius line?
