For instance :- take downward side as positive.
s = +100m
g = +10m/s²
u = 0
v = ?
Apply v²-u²= 2as
Plug-in the values , we get :-
v²-0 = 2×10×100
v² = 2000
=> v = ±√2000 m/s
v can't be negative as motion is in positive direction!
Hence v = √2000 m/s
s = +100m
g = +10m/s²
u = 0
v = ?
Apply v²-u²= 2as
Plug-in the values , we get :-
v²-0 = 2×10×100
v² = 2000
=> v = ±√2000 m/s
v can't be negative as motion is in positive direction!
Hence v = √2000 m/s
