Car A is traveling at the constant speed of 64 km/h as it rounds the circular curve of 285-m radius and at the instant represented is at the position θ = 45°. Car B is traveling at the constant speed of 94 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. 3 decimals.
