Question

Question is asking for the: r double dot, theta double dot

and also, r double dot =1.98 m/s^2 and theta double dot 0.0144 rad/s^2 are incorrect.

Thank you!!

Car A is traveling at the constant speed of 47 km/h as it rounds the circular curve of 205-m radius and at the instant represented is at the position e traveling at the constant speed of 60 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 the pole moving with B. For this instant determine the values of and A as measured by an observer in car B 49°. Car B is with 205 m
