Projectile motion at an angle problem

[Anton338]

Homework Statement

A ball is thrown at a 40 degree angle from the horizontal over level ground. If the initial velocity of the ball is 28 meters per second, how far does the ball travel before hitting the ground?

Homework Equations

X=Vi*t+(1/2)At^2
Ttotal=(2Vyo)/g
sine/cosine/tangent
A^2+B^2=C^2

The Attempt at a Solution

Vyo = 18m/s because Sin(40)*28
Vxo = 21.4m/s because Cos(40)*28

aaand I'm stuck. What do I need? Where do I go?
SO CONFUSED :P

Thanks Forum
