1) For traveling a height of h/2 from rest the time taken is:
         h/2 = 0 * t1 + 1/2 g t1²
         =>  t1 = √(h / g)
    Speed of the body at this height =>  v = 0 + g * √(h/g) = √(g h)
 
2)  For traveling the remaining height of  h/2 at the above uniform speed:
         h/2 = √(g h) * t2
     => t2 =  1/2 * √(h / g)

Total time taken to reach the ground:  3/2 * √(h / g)
