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 \[S=4\times 6=24m\]
