Answer 1

Two bodies of different masses Ma and Mb are dropped from two different heights, i.e. a and b. The ratio of time periods taken by two masses to drop through these distances is...?

Answer:

At a free falling time of falling depends on height and does not depend on a mass of bodies.

$H = gt^{2} / 2$ where $g = 9,8\mathrm{m / sec}^2$ -acceleration of free falling. Therefore

$$t = \sqrt {\frac {2 H}{g}}$$ $$\frac {t 1}{t 2} = \sqrt {\frac {H 1}{H 2}}$$
