Suppose vectors u and v lie in the xy-plane (the 2- component of each vector is zero). Now suppose x- and y- components of u and the y-component of v are all positive, whereas the x-component of v is negative. Assuming the coordinate axes are oriented in the usual positions, in which direction does u x v point?

The route followed by a hiker consists of three displacement vectors A,B ,c Cand . Vector  A is along a measured trail and is 1550 m in a direction 25.0° north of east. Vector B is not along a measured trail, but the hiker uses a compass and knows that the direction is 41.0° east of south. Similarly, the direction of vector C is 10.0° north of west. The hiker ends up back where she started, so the resultant displacement is zero, or  A+  B+ C = 0. Find the magnitudes of vector B and vector C .

A unit vector m is along the positive x-axis and the unit vector n in quarant II. The angle betweenthem is 104°. Draw a vector diagram of 3n-2m and then find the magnitude of |3n+2m|, correctto the nearest tenth.
