a stone is dropped from the edge of a roof
¡) how long does it takes to fall 4.9 m
(taking g as 9.8m²)​

Answer 1

$formula \: = time = \: \sqrt{ \frac{2d}{g} }$
where d=distance = 4.9 m
g= 9.8
substituting this value in formula
$\sqrt{ \frac{2 \times 4.9}{9.8} }$
=
$\sqrt{ \frac{9.8}{9.8} } = 1$
so the answer is 1m
