A car starts out at the north end of a circular track 1.50 km in diameter and travels in a straight line to the east end and then travels in a straight line to the south end at a constant speed of 10.5 m/s. At the south end there is a straight road leading to the north end. The car starts from rest at the south end following the road and accelerates at 0.39 m/s2. (a)...
