Question

As a High Point Univ. student walks to her dorm on the sidewalks, she has three successive displacement vectors (i.e. one right after the other): Delta rightarrow rA = (19 m)ihat Delta rightarrow rB = (16 m)jhat Delta rightarrow rC = (11 m)ihat + (17 m)jhat What is the x-component of the total displacement of the student? m What is the y-component of the total displacement of the student? m What is the magnitude of the total displacement of the student? m What is the angle between the displacement vector (i.e. total displacement) and the horizontal axis? degree

Explanation / Answer

x component = 19 +11=30 (summing i components) y component = 16+17=33 (summing j components) magnitude = 44.598 angle = 47.72
