Question

A body is projected vertically upwards. The times corresponding to height h while ascending and while descending are $t_1$ and $t_2$, respectively. Then, the velocity of projection will be
(take g as acceleration due to gravity)

• A. $\frac {g \sqrt {t_1t_2}}{2}$
• B. $\frac {g(t_1+t_2)}{2}$
• C. $g \sqrt {t_1t_2}$
• D. $g \frac {t_1t_2}{(t_1+t_2)}$

Answer 1

Answer: (B)

$\frac {g(t_1+t_2)}{2}$

Answer 2

The correct option is (B): $\frac {g(t_1+t_2)}{2}$.
