Ok I am stuck on how to solve this problem and i don't have physics again until next week. The question is:

A ball is thrown horizontally at 22m/s from the roof of a building lands 36.0m from he base of the building. How tall is the building?
 
Physics news on Phys.org
What have you attempted so far?
 
ive tried nothing and I am all out of ideas
 
I can give you some hints. Resolve the ball's motion into the horizontal and vertical components.

For the horizontal component, you already have the initial velocity and the horizontal distance traveled (36.0m). Find the time taken for the ball to fall.

Now that you have this, use it for the vertical component. In the following formula:

s = ut + 0.5a(t^2)

s is the vertical height.

You should be able to solve your problem now. :)
