An automobile moves on a circular track of radius 1.02 km. It starts from rest from the point (x, y ) = (1.02 km, 0 km) and moves counterclockwise with a steady tangential acceleration such that it returns to the starting point with a speed of 29.3 m/s after one lap. (The origin of the Cartesian coordinate system is at the center of the circular track.) What are the car's position and velocity vectors when it is one-eighth of the way around the track? Express the vectors in terms of the unit vectors along the x- and y-axes. r = ( _____ i + _____ j) km v = ( _____ i + _____ j) m/s
