Abstract

En aquest article analitzem el problema de si és millor córrer o caminar lentament sota la pluja per mullar-nos el mínim possible. Es tracta d'un problema que ha atret l'atenció de molts científics i que ha estat molt debatut. Presentem la resolució en diverses situacions: sense vent, amb vent de cara, amb vent posterior i amb vent lateral. Es modelitza la persona que camina sota la pluja com un paral•lelepípede. Amb el resultat obtingut podem determinar la quantitat d'aigua, en massa, que recollirà cadascuna de les superfícies de la persona que camina sota la pluja.
