I had a small question regarding water slides. Imagine 2 identical water slides, let the slides be a fun one as in with all the ups and downs, of course not going higher than the initial height! If two people have a race: would their weights matter? If so who would win? Also if they were of exactly the same weight is there any way that there could be only one winner by considering his body movement while sliding down. PS they both are on mats or something hence constant friction. Sorry for making the question sound so... immature!
