## Homework Statement

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.

## Homework Equations

x=X0 + V0t + 1/2(a)(t^2)

Im stuck :/
