two balls are thrown with equal speeds from the top of a cliff of height H. one ball is thrown upward at an angle @ above the horizontal. the other ball is thrown downward at an angle # below the horizontal. show that each ball strikes the ground with same speed and find that speed in terms of H and the initial velocity v'.(adsbygoogle = window.adsbygoogle || []).push({});

hope that some one will solve this problem for me . with gratitude
