If I jump into the water from a cliff, what is the ratio of the height of the cliff to the depth of the water so that I won't get hurt? There is also a formula. Simple.
Without considering the air resistance, suppose the cliff height is H, the water depth is H, and the average resistance in the water is F, and it will slow down to 0 when entering the water, just reaching the bottom. According to kinetic energy theorem:
0=mg(H+h)-Fh .H/h=(F-mg)/mg。
Considering the air resistance, let the resistance be f.
Similarly: H/h=(F-mg)/(mg-f)
