v^2=u^2+2as
=2×4×800
V=80m/s
=2×4×800
V=80m/s

U=0m/s
a=4m/s^2
s=800m
V=
2as=v^2-u^2
2(4)(800)=v^2-(0)^2
6400=v^2-0
6400+0=v^2
6400=v^2
now take the square root of 6400
80=v
Ans.80m/s is the velocity
a=4m/s^2
s=800m
V=
2as=v^2-u^2
2(4)(800)=v^2-(0)^2
6400=v^2-0
6400+0=v^2
6400=v^2
now take the square root of 6400
80=v
Ans.80m/s is the velocity
but i have marked already sorry
