Question:

For the conditions of Prob. 2/201, determine the values of r¨ and θ¨ as measured by an observer in car B at the instant represented. Use the results for r˙ and θ˙ cited in the answers for that problem.


Data from Prob. 2/201

Car A is traveling at the constant speed of 60 km/h as it rounds the circular curve of 300-m radius and at the instant represented is at the position θ = 45°. Car B is traveling at the constant speed of 80 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.
