In the figure below, what is the minimum initial speed of the dart if it is to hit the monkey before the monkey hits the ground, which is 12.2 m below the initial position of the monkey, if x is 48 m and h = 11 m? (Ignore any effects due to air resistance.)

From my calculations I have that it takes 1.6s for the monkey to fall 12.2m.
x=X0 + V0t + 1/2(a)(t^2)
