Answer 2

HEY MATE HERE IS UR ANSWER-:

LET

》X =100 m

》h =10m

using 2nd equation of motion

$h = ut + \frac{1}{2} g {t}^{2}$

☆ansume g =10m/s2☆

NOW

we will get ,

$t = \sqrt{ \frac{2h}{g} }$

$t = \sqrt{ \frac{2 \times 10cm}{10m {s}^{ - 1} } }$

CHANGE cm in meter

$t = \sqrt{ \frac{2 \times 0.1m}{10m {s}^{ - 1} } }$

t= 0.14s

●we will use again motion equation●

$v = \frac{x}{t}$

$v = \frac{100m}{0.14s} \\ \\ = > 707.11 m {s}^{ - 1}$
