(5 pts) (i) It has a constant velocity (ii) It has no acceleration (iii) It has an acceleration directed towards the center of the path. (iv) It has an acceleration tangential to the path. (b) What is the ideal speed to take a 75 m radius curve banked at a 40.0° angle?

6. (a) When a car moving in a circular path, at a constant speed then It has an acceleration directed towards the center of the path.
Because on a circular path with constant speed, there is no tangential accele acting on the body. Only radial acceleration which is centripetal accleration acts on the body and is directed towards the centre.
So option (iii) is correct option.
