Text Transcription:

u dot v

u dot u

||u||^2

(u dot v) v

u dot(2 v)

u=langle-4,8 rangle, v=langle 7,5 rangle

Step-by-Step Solution:

Step 1 of 5) To evaluate the integrals in Equations (5), we picture the plate in the coordinate plane and sketch a strip of mass parallel to one of the coordinate axes. We then express the strip’s mass dm and the coordinates (x , y ) of the strip’s center of mass in terms of x or y. Finally, we integrate y dm, x dm, and dm between limits of integration determined by the plate’s location in the plane.
