seriously , this is your complete question.
okay, let us think about given equation ,
here it is given that 0 = u² + 2(-g)s ,
or, 0 = u² - 2gs
or, u² = 2gs
or, u =
hence, according to your question, answer should be u = √{2gs}.
well, I think question is like that , “A body or object is thrown vertically upwards with speed u m/s, it becomes rest after traveling s m. then find initial velocity of body or object ?”
final velocity of body , v = 0
initial velocity of body = u
distance travelled by body = s
using Newton's 3rd equation of motion,
v² = u² + 2as
a = -g [ because body moves under gravity]
0 = u² + 2(-g)s
then, final you will get u = √2gs}.
I hope you get your answer
cheers !
