heyy bro ur question was incomplete there is unable to see the value of height but dont worry follow my step u will get answer of ur query.
From the equations of motion of a single particle we know that,
S = u.t + (g.t^2)/2
Where S is the distance, u is initial velocity of the particle, t is time taken by the particle to co ver the distance S, and g is the acceleration due to to gravity.
So after substituting their respective values in the above equation, we get-
On simplifying we get-
t=?
Now, from another equation of motion we get-
v = u + a.t
Where u and v are the initial and final velocities of the particle respectively, a is acceleration, and t is time.
Now, afer substituting their respective values here, we get-
v = ? then after
ke=1/2mv^2 put formula value u will get answer......i hope it will help u
