Question
Car A is traveling at the constant speed of 58 km/h as it rounds the circular curve of 350-m radius and at the instant represented is at the position θ = 42°. Car B is traveling at the constant speed of 69 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.
For this instant determine the values of r˙ and θ˙ as measured by an observer in car B.
Answers:
r˙ = | m/s |
θ˙ = | rad/s |
