A1.2.4.HeightEstimations
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. 4. (a) Using the same coordinate system assumed in Eq. 4-22, we solve for y = h: which yields h = 51.8 m for y0 = 0, v0 = 42.0 m/s, 0 = 60.0° and t = 5.50 s. ................
