Question

A body falling from height \(H\) takes time \(T\) seconds to reach the ground. The time taken to cover the second half of height is

• A. \(\frac{T}{\sqrt{2}}\)
• B. \(\sqrt{2}T\)
• C. \(\frac{\sqrt{2}-1}{\sqrt{2}}T\)
• D. \(\frac{1}{\sqrt{2}-1}T\)

Hint:

For free fall from rest, distance is proportional to square of time: \(s\propto t^2\).

Answer 1
