# A body thrown vertically up to reach its maximum height in t seconds. The total time from the time of projection to reach a point at half of its maximum height while returning (in seconds) is

$\begin {array} {1 1} (1)\;\sqrt 2 t & \quad (2)\;\bigg(1+ \frac{1}{\sqrt 2}\bigg)t \\ (3)\;\frac{3t}{2} & \quad (4)\;\frac{t}{\sqrt 2} \end {array}$

$(2)\;\bigg(1+ \frac{1}{\sqrt 2}\bigg)t$
