Question
Car A is traveling at the constant speed of 67 km/h as it rounds the circular curve of 320-m radius and at the instant represented is
at the position e = 46°. Car B is traveling at the constant speed of 98 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 0 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.
