    A car, moving with a speed of 50 km/hr, can be stopped by brakes after at least 6m. If the same car is moving at a speed of 100 km/hr, the minimum stopping distance is [AIEEE 2003]

    A)             6m      

    B)             12m

    C)             18m    

    D)             24m

    Correct Answer: D

    Solution :

                    \[S\propto {{u}^{2}}\]. Now speed is two times so distance will be four times \[S=4\times 6=24m\]
