Answer: Frictional Force acts on a speeding vehicle making it skid when sudden brakes are applied.
Explanation:
Consider a car of weight W moving on a horizontal road.
Vertical equilibrium requires N = W.
What happens when the brakes are applied?
If the car skids, then the retarding frictional force fk = μkW. If the car does not skid, then the frictional force has a maximum given by fmax = μsW.
Because μs > μk, fmax > fk. The maximum effect of braking without skidding exceeds the effect of braking with skidding.
