1. The problem statement, all variables and given/known data
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.

2. Relevant equations
V2 Equation

3. 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.

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

where s=displacement and s0= initial displacement.

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