## Homework Statement

A player kicks a football from ground level with an initial velocity of 27.0 m/s, 30.0° above the horizontal, as shown below. Find the ball's hang time, range, and maximum height. Assume air resistance is negligible.

## Homework Equations

These are the equations that I have been given by my teacher:

(Final velocity of y/x) = (Initial velocity of y/x) + (Acceleration of y/x)(Time)

(Final velocity of y/x)^2 = (Initial velocity of y/x)^2 + 2(Acceleration of y/x)(Displacement of y/x)

(Displacement of y/x) = (Initial velocity of y/x)(Time) + .5(Acceleration of y/x)(Time^2)

I'm not sure if there are any equations I'm missing, and if I'm missing one, it might be a giant cause of my problem.

## The Attempt at a Solution

I have no idea how to solve this equation. I've found the initial vertical and horozontal components of the initial velocity. Vi,x = 23.4 m. Vi,y = 13.5 m. But to find the hang time, range, and height, I'm lost.
