If the cat in Problem takes 45 minutes to complete the 120-m displacement and 17 minutes to complete the 72-m displacement, what arc the magnitude and direction of its average velocity during this 62-minute period of time?
Problem
In its daily prowl of the neighborhood, a cat makes a displacement of 120 m due north, followed by a 72-m displacement due west. (a) Find the magnitude and direction of the displacement required for the cat to return home. (b) If, instead, the cat had first prowled 72 m west and then 120 m north, how would this affect the displacement needed to bring it home? Explain.
