When a car of mass `1000kg` is moving with a veocity of `20ms^(-1)` on a rough horizontal road its engine is switched off. Hwo for does the car move before it comes to rest if the coefficient of kintic friction between the road and tyres of the car is `0.75` ? .

Text Solution

Verified by Experts

Here `v =20ms^(-1), mu_(k) = 0.75, g =10ms^(-2)`
Stopping distance `S = (v^(2))/(2mu_(k)g) =26.67m` .
