A bow-hunter is stalking a buffalo from the top of a cliff (point A). The animal is standing at rest at the base of the cliff, at point X, on the level ground. The buffalo sees the hunter and begins to run directly away from the cliff, reaching its (constant) maximum speed before passing point B. Exactly Dtrun s after the buffalo passes point B, the hunter shoots an arrow and hits the animal. The arrowâ€™s initial path is directed at an angle q below the horizontal. The arrowâ€™s complete flight, from release to hitting the animal, takes Dtarrow s. The horizontal distance between points A and B is xAB m. The vertical distance between points A and B is yAB m. Ignore the heights of the buffalo and the hunter. Find the buffaloâ€™s maximum speed (the speed it was running when it was hit). Keep in mind that you may consider these values as known: Dtrun, q, Dtarrow, xAB, yAB, g.

No bow hunter would hunt this way. Check with PETA.
