In the figure, a stone is projected at a cliff of height h with an initial speed of 49.0 m/s directed at an angle 0 = 66.0 above the horizontal. The stone strikes at A, 5.11 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/52.
