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 is (g is acceleration due to gravity)

Options:

Answer:

Solution:

time take by particle to move from O to B is $= t_{1} + \frac{( t _{2} - t _{1} )}{2} = \frac{( t _{1} + t _{2} )}{2}$

$0 = u - g \times \frac{( t _{1} + t _{2} )}{2} \Rightarrow u = \frac{g ( t _{1} + t _{2} )}{2}$
