Question

This question was a concept question on my physics test.

Answer 1

Answer:

t√2.

Explanation:

Given that both are rest at initial position.

The time taken by stone A is t

h= 1/2 g t²            ----------1

Lets time taken by stone B is t'

2 h= 1/2 g t'²             -----------2

From equation 1 and 2

2 h= 1/2 g t'²  

2 x  1/2 g t²  = 1/2 g t'²  

t'²=2 t²

t' = t√2

So the answer is t√2.

e. sqrt(2) .t
