Consider the two vectors M = (a, b) = ai+bi and N = (c,d) = ci+di, where

Consider the two vectors M = (a, b) = aˆi+bˆi and N = (c,d) = cˆi+dˆi, where a = 4, b = 4, c = −3, and d =3. a and c represent the x-displacement and b and d represent they- displacement in a Cartesian xy coordinate system.

a) What is the magnitude of the vector product M × M ?
b) What is the magnitude of the vector product M× N ?

c) What is the direction of the vector product M× N?
1. in the yz plane, but not along y or z
2. along the x-axis
3. none of these since its direction cannot be determined
4. in the xz plane, but not along x or z
5. in the xy plane, but not along x or y
6. along the z-axis
7. along the y-axis
