The Problem of the Amount of Rain Falling on People Walking in Rain
QIU Yang-cong
Abstract：When people walk in rain,the problem of at what speed they have the minimum of rain falling on them arouses people's interest.Many scholars have tried to give the solution by building a mathematic model. Some references offer straightforward and innovative ways,but those ways have some shortcomings respectively. Through adopting,correcting and supplementing the ways in the references,this paper combines the advantages and compensates for the weaknesses.It gives more rigorous solutions to the problem of rain amount through three-dimension and monotonicity analyses,and makes deeper analyses by using Matlab to arrive at valuable conclusions.
