\fIf u 6 and w are coplanar, then w is perpendicular to both and w and since u 6 and w are in the same plane, Eg.3: Determine if the following vectors are coplanar. u = 2696- 4 6 = [36- 46] and w = [, 62 6- 4]Applications of the Dot Product and Cross Product When a force is acting on an object so that the object is moved from one point to another, we say that the force has Eg.1: A rickshaw driver pulls his cart at an angle of 30 with the horizontal. If his current customer requires him to pull up on the rickshaw handles with a force of 60 N, and the trip is a total of 750 m, how much work, in J, has the rickshaw driver done over the course of this trip
