Car A is traveling at the constant speed of 64 km/h as it rounds the circular curve of 360-m radius and at the instant represented is at the position 0 = 49°. Car B is traveling at the constant speed of 95 km/h and passes the center of the circle at this same instant. Car A is located with respect to car B by polar coordinates r and O with the pole moving with B. For this instant determine va/B and the values of i and O as measured by an observer in car B. 360 m B
