In Fig. 4-34, a stone is projected at a cliff of height h with an initial speed of 45.0 m/s directed at an angle θ0 = 62.0° 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.

h=5.37[45*sin62-(9.81*5.37/2)]=71.92ng=[45^2-(2*45*9.81)+sin62+(9.81*5.37)^2]^1/2=62.59m/smax. height=[45^2*(sin62)^2/(2*9.81)]=80.46m ans; a.height h is 71.92mb.speed g is62.59m/sc.maximum…
