very simple. !!!
u = 49 m / s
now for the time => given by formula => 2U g
so time will be => 2× 49 / 9.8
=> 10 sec
time of accent = time of decent = 5 sec
hence total time taken is = 10 sec
hope it help you !!!

Answer:
Hi friend
--------------
Your answer
---------------------
here,
Final velocity = V = 0 m/s ,
Initial velocity = u = 49 m/s ,
Acceleration due to gravity = a = g = - 9.8 m/s² ,
Height = s = ?
So,
------
v² - u² = 2as
=> v² - u² = 2×g×s
=> (0)² - (49)² = 2 × (- 9.8) × s
=> - (49 × 49) = - ( 2 × 9.8 × s)
=> s = (49 × 49) / (2 × 9.8)
=> s = 122.5 m
