Homework Statement
A stone is thrown upward from the top of a building at an angle of 30.0 degrees to the horizontal and with an initial speed of 20.0 m/s. The height of the building is 45.0 m.
Where does the stone strike the ground?
Homework Equations
[itex]v_{x0} = v_0\cos{\theta_0}[/itex] where [itex]v_{x0}[/itex] is the original velocity x component, [itex]v_0[/itex] is the original velocity, and [itex]\theta_0[/itex] is the original angle (not sure if we use this)
Also [itex]v_{y0}[/itex] is the original velocity y component.
The Attempt at a Solution
I'm not sure how to proceed here. We're finding horizontal distance, so no equations concerning [itex]v_{y0}[/itex] would work, and [itex]v_{x0} = v_0\cos{\theta_0}[/itex] only works if the vertical distance is the same as the original vertical distance..
