How Do You Calculate Projectile Motion in Physics?

[Smarties07]

An AP physics student is standing on the top of a building 30 m tall. If the student throws an object at a speed of 5m/s at an angle of 30 degrees to the horizontal, a)what is the object's maximum height and b)how far away from the building does the object hit the ground?

I just need help starting it...therefore I can't really show any work at this point...

Welcome to PF.

You're going to need to show some work.
