Answer rating: 100% (QA)
To solve this problem we can analyze the motion of the rock in the horizontal and vertical directions separately using the equations of motion a To find the height of the cliff we will use the vertical motion equation h vi t 05 a t2 Where h height of the cliff vi initial vertical velocity 18 ms sin25 t time taken for the rock to land 42 seconds a acceleration due to gravity 981 ms2 taking downward direction ...
