1.43. Set Up: In each case, use a sketch (Figure 1.43) showing the components and the resultant in order to determine the quadrant in which the resultant vector lies. The component vectors add to give the resultant. Figure 1.43 Solve: (a) and (b) and (My calculator gives and (c) and (My calculator gives and (d) and (My calculator gives and 1.44. Set Up: For each vector, use the relations and Solve: For vector For vector For vector 1.45. Set Up: For parts (a) and (c), apply the appropriate signs to the relations and For (b) and (d), find the magnitude as and the direction as u 5 tan 2 1 1 R y / R x 2 .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
