A car moving with a speed of can be stopped by brakes after at least . If the same car is moving at a speed of the minimum stopping distance is :
Step 1: Given
Speed of the car,
Stopping distance,
Final velocity,
Step 2: Determine the acceleration of the car
Using the third equation of motion,
Step 3: Determine the minimum stopping distance for
Using the third equation of motion again,
Therefore, option B is the correct option.
