In the figure, a stone is projected at a cliff of height h with an initial speed of 44.0 m/s directed at an angle 80 = 52.0 above the horizontal. The stone strikes at A, 5.37 s after launching. Find (a) the height h of the cliff, (b) the speed of the stone just before impact at A, and (c) the maximum height H reached above the ground. Use g=9.80 m/s.
