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:

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

There will be no friction between the road and the tires as the centrifugal force will be more than the frictional force because the speed is 15 mph over the design speed of the curve

There will be no friction between the road and the tires as the centrifugal force will be more than the frictional force because the speed is 15 mph over the design speed of the curve
