How Long Does a Horizontally Shot Ball Stay Airborne?

[IneedHelp:-)]

Homework Statement

A ball is shot horizontally at a speed of 10 m/s from a height of 2 meters. How long is the ball in the air and how far horizontally does it travel before it hits the ground.

Homework Equations

V2 Equation

The Attempt at a Solution

I am assuming I need to find both the X and Y components right? I know that the final Y velocity must be 0 because it stops at the top of its trajectory. What is throwing me off is the 2 meters it starts at as well as how I am going to get the horizontal distance.

Homework Equations

V2 Equation

$$s=s_o +ut-\frac{1}{2}gt^2$$


where s=displacement and s₀= initial displacement.

So considering vertically, what is s₀? and you want to find the 't' for which s=0.
