Easy

$(\frac{1}{2})(m)*(v_i)^2+m*g*h_i=(\frac{1}{2})m*(v_f)^2+m*g*h_f$

$minus \space\ m*g*h_f$ from both sides

$(\frac{1}{2})(m)*(v_i)^2+m*g*h_i-m*g*h_f=(\frac{1}{2})m*(v_f)^2$

times both sides by 2/1

(m)*(v_i)^2+2m*g*h_i-2m*g*h_f=m*(v_f)^2

square root both sides

$\sqrt{(m)*(v_i)^2+2m*g*h_i-2m*g*h_f}=v_f$

$v_f=\sqrt{(m)*(v_i)^2+2m*g*h_i-2m*g*h_f}$
