Question: choose the correct answers 1 what are the polar coordinates...

Question details

Choose the Correct answers: 1. What are the polar coordinates of the vector 3i-2j? (a) (3.6; 33.7) (b) (3.6; 146.3*) (c) (3.6;-33.7) (d) (4.2; 33.7) (e) (4.2;-33.7) 2. If vector A-)=3.21+4Sf and vector B->=5.71-19 , where i^ and jare the units vectors along the x and the y directions respectively. If C-〉-3A->-28→, calculate the angle vector C-> makes with respect to the +x axes. (a) -840 (b) -96 (c) 849 (d) 969 (e) -6
