Question: Two balls are thrown with equal speeds from the top of a cliff of height H. One ball is thrown upward at an angle

Two balls are thrown with equal speeds from the top of a cliff of height H. One ball is thrown upward at an angle α above the horizontal. The other ball is thrown downward at an angle β below the horizontal. Show that each ball strikes the ground with the same speed, and find that speed in terms of H and the initial speed v₀.
