Hello guys. I was wondering about slides in a water a park and how they calculate the landing distance to predict where a person who land in order to keep them safe by landing them in the water of course... and also at an appropriate speed. So I want to do an experiment on this by making a model slide and sliding a controlled object down it. What are some things I should consider? and What are some variables I can change? Maybe something like launch angle vs distance? and find out the optimum angle for the shortest distance or something like that? If you can provide links to experiments that people have already done , it would be greatly appreciated as well. or maybe even the pool water depth with speed of entry/launch of angle? Thanks!
