From the top of a tall building, a gun is fired. The bullet leaves the gun at a speed of 340 m/s, parallel to the ground. The bullet puts a hole in a window of another building and hits the wall that faces the window. (y = 0.42 m, and x = 7.2 m.)Determine the distances D and H, which locate the point where the gun was fired. Assume that the bullet does not slow down as it passes through the window.
