[19] Three vectors are given by -6i, =9j, and c-(-3i+4). (a) Find the magnitude and
direction of the resultant vector. (b) What vector must be added to these three to make the
resultant vector zero?
[20] A particle moves from a point in the xy plane having Cartesian coordinates (-3.00, -5.00)
m to a point with coordinates (-1.00, 8.00) m. (a) Write vector expressions for the position
vectors in unit-vector form for these two points. (b) What is the displacement vector?
