We are given the following information
Horizontal distance covered = 24 m
Initial speed = 8 m/s
We are asked to find the height of the cliff.
Let us first find the time.
Where △x is the horizontal distance covered and vix is the initial horizontal speed of the diver.
So, the time is 3 seconds.
The vertical distance covered by the diver is given by
Where g is the acceleration due to gravity that is 9.81 m/s^2
Therefore, the height of the cliff is 44.145 m
