Current Attempt in Progress In the figure, a stone is projected at a cliff of height h with an initial speed of 50.0 m/s directed at an angle 0 = 68.0 above the horizontal. The stone strikes at A, 5.50 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/s2. H (a) Number Units (b) Number Units (c) Number Units
