A body is thrown vertically upwards with velocity $u$. The distance travelled by it in the fifth and the sixth seconds are equal. The velocity $u$ is given by.........$m/s$ ($g = 9.8\, m/s^{2}$)

A body is thrown vertically upwards with velocity $u$. The distance travelled by it in the fifth and the sixth seconds are equal. The velocity $u$ is given by.........$m/s$ ($g = 9.8\, m/s^{2}$)
The given condition is possible only when body is at its highest position after $5 $ seconds
It means time of ascent = $5\, sec$
and time of flight $T = \frac{{2u}}{g} = 10$ $⇒$ $u = 50\;m/s$
