NEET Physics Speed & Velocity MCQ Question
What happens to the stopping distance of a vehicle when its initial velocity is doubled, assuming the same deceleration?
It increases by a factor of 4.
It remains the same.
It decreases by a factor of 2.
It increases by a factor of 2.
Correct Answer
Detailed Explanation
According to the equation of motion v^2 = v_0^2 + 2ax, the stopping distance is proportional to the square of the initial velocity. Therefore, doubling the initial velocity increases the stopping distance by a factor of 4.
