In Denver, children bring their old jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground (Figure 4-18). Suppose that the tower height is h = 8.00 m, and that the bulls-eye's horizontal distance is d = 4.1 m from the launch point. If the pumpkin is thrown horizontally, what is the launch speed needed to hit the bulls-eye? (Neglect air resistance.)
