Document Summary
Position is a location described with the distance and direction from a reference point. In 2 dimensional space, it can be expressed as r = x x + y y. Displacement is the difference between the final and initial positions. In 2 dimensional space, it can be expressed as r = ri rf . Rearranging the above equation, you can see that f = i + r r r. 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) b) Find the magnitude and direction of the displacement required for the cat to return home. If, instead, the cat had first prowled 72 m west and then. Average velocity in 2 dimensions is defined to be v av r. Dividing a vector with a scalar changes only the magnitude of the vector, leaving the direction the same.
