9. H SSM From the top of a tall building, a gun is fi red. The bullet leaves
the gun at a speed of 340 m/s, parallel to the ground. As the drawing shows,
the bullet puts a hole in a window of another building and hits the wall that
faces the window. Using the data in the drawing, determine the distances D
and H, which locate the point where the gun was fi red. Assume that the bullet
does not slow down as it passes through the window.

I don't see a drawing but perhaps the smart tutors on this site can use the description to figure it out.
If the bullet flew for time t seconds,
the vertical speed is -9.8t
the horizontal speed is 340
the vertical drop is -4.9t^2
the horizontal distance is 340t
and why do you always type "fi red" instead of "fired"?
