(2) 8
(3) 2 s
(4) 10s​

Answer 1

The total flight time will be 8 seconds.

Answer 2

Answer: 8 seconds

Explanation:

if the stone takes 4 seconds to reach the topmost point from the ground, it will again take 4 seconds to reach the ground...so the total time of flight will be : (4+4=) 8 seconds....

NOTE: In free fall the time taken to reach topmost point= time taken to descend downwards...
