_{1}from the edge. A second ball moving with the same speed rolls of a self of height 2h and strikes the floor a distance x

_{2}away from the edge. Determine the ratio of distances x

_{1}/x

_{2}.

[tex]\Delta[/tex]x=V

_{x}t

[tex]\Delta[/tex]y=vt +1/2st

^{2}

The horizontal motion of the ball is constant and, therefore, not affected by the height from which it rolls. But I cannot figure out how to formulate the ratio of the distances. I know that time relates the two equations of motion and that because the ball is rolling it has no initial vertical velocity and that since it is free fall the acceleration would be the same for the two equations. I just can't seem to get the equation to make sense when I write it out. Any help would be greatly appreciated. Thanks!
