Car A is traveling at the constant speed of 48 km/h as it rounds the circular curve of 295-m radius and at the instant represented is at the position θ = 49°. Car B is traveling at the constant speed of 64 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 θ with the pole moving with B. For this instant determine vA/B and the values of r˙ and θ˙ as measured by an observer in car B. Find vA/B and vA/B. vA/B = (  ______i +  ____j) m/s vA/B = ______ m/s
