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

Solution & Step-by-step Explanation

Stopping distance s = \frac{u ^{2}}{2 a} . Assuming constant retardation a : s \propto u^{2} If speed u is doubled (100/50 = 2), the stopping distance becomes 2^{2} = 4 times.New distance = 4 \times 6 m = 24 m .

Try it yourself before checking the explanation above.

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

12 m

18 m

24 m

6 m
