Statement I: The driver of a moving car sees a wall in front of him. To avoid collision, he should apply brakes rather than taking a turn away from the wall. Statement II: Frictional force is needed to stop the car or taking a turn on a horizontal road.

A bob suspended from the ceiling of a car which is accelerating on a horizontal road. The bob stays t rest with respect to the car when the string is making an angle theta with the vertical.The linear momentum of the bob as seen from the road is increasing with momentum? If not, where is the external force which changes the linear momentum?
