6           63.6

8          6.4

10         -90

12          -225.6

The ball is at the same height as the building  when Height is 0 as  height is measured from building height

0 is at  t = 0

and 0 is   6.4  & - 90  Hence between  8 & 10 sec

The ball is at the same height as the building between 8 and 10 seconds after it is thrown - TRUE

The height of the ball decreases and then increases  False  

as its 1st  increases and then decreases

The ball reaches its maximum height about 4 seconds after it is thrown

TRUE   as  in table max value 81.6 at 4 sec

Ball goes  till - 225.6  Hence minimum height of Building is 225.6 m
