Question

Please provide correct solution :​

Answer 1

Explanation:

it takes time “T” to reach the ground then,

H = 0.5gT²

T = √(2H/g)

If it takes time “t” to travel first half of the journey then,

0.5H = 0.5gt²

H = gt²

t = √(H/g)

Time taken to cover second half of the journey is = T - t

= √(2H/g) - √(H/g)

= √(H/g)×(√(2) - 1)
