Question
If a speeder takes a banked turn in a road at 15 mph over the design speed of the curve, the frictional force between the road and the tires will:
Question 8 options:
There will be no friction between the road and the tires
The friction will be directed up the bank of the road
The friction will be directed down the bank of the road
The friction will be directed back behind the vehicle
There will be no friction between the road and the tires
The friction will be directed up the bank of the road
The friction will be directed down the bank of the road
The friction will be directed back behind the vehicle
Explanation / Answer
The frictional force in a banked turn counteracts the centripetal force which originates as a result of circular motion. Since centripetal force is always directed towards the center and down the bank of the road, the frictional force will be directed up the bank of the road.
