Solution Verified by Toppr

Correct option is C)

The object has flight height (s−5) m in

2 10 ​ s= 5s

The object is descending at the same time= 5s

Using, s=ut+ 2 1 ​ at 2 s−5=0×5+ 2 1 ​ ×9.8×5 2 s=127.5 m

Time taken to travel vertically 127.5 m,

=>127.5=0×t+ 2 1 ​ ×9.8×t 2 t 2 =26.02s t= 5.1 s

Therefore total time of flight is= 2×5.1 = 10.2s

104 ​ s
