Given the three vectors A = i, B = i- j, and C = k Find A.(BXC).
Find the resultant force vector,R, of the three vectors A,B, and C (i.e., add the vectors), if the magnitude of vector A is 10N, the magnitude of vector B is 17N, and the magnitude of vector C is 9N. Your answer should be in the form R = Rx i+ Ry j,
where you determine Rx and Ry, and where i, and j are the unit vectors along the x, and y axis, respectively.
