Physics 117A PROBLEM SET #1 Assigned: Wed.. 8/26/09 Young & Freedman Chapters 1 & 2 Turn in no later than 5:00 PM Thurs. September 3 Show all your work, and explain your reasoning. It is usually best to solve problems algebraically and only insert numerical values as the last step if a numerical answer is required. After you have solved a problem, pause and ask yourself whether the answer seems plausible; include with your solution a statement regarding the plausibility of the answer. See the grading scheme and an example of a good problem solution on the course web page (Topics Homework) BOX YOUR FINAL ANSWERS. While we encourage free discussion of the homework, all assignments are to be completed individually. Copying will not be tolerated. 1.

Vector B has magnitude 2.30 and lies in the xy plane pointing at an angle 60º from the – x axis and 30º from the –y axis. Vector C = A + B .

### 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.
