Problem An explorer in Antarctica leaves his shelter during a whiteout. He takes 50 m northeast, next 180 m at 72° north of west, and then 150 m due south. Save the explorer from becoming hopelessl lost by giving him the displacement, calculated by using the method of components, that will return him to his shelter. Solution By vector-component approach, we list down the given in a table as follows: Given x-component (w/ sign direction) y-component (w/ sign direction) A = 50 m NE m m B = 180 m 72° NW m C = 150 m s m Resultant m m Thus, the magnitude of the resultant vector is R = m With a direction of O NW Therefore, the vector needed for him to successfully get back home is Rhome - O SE m
