Physics 211 Spring 2012 Syracuse University Homework Problem Set 2 p.1 Physics 211 Problem Set 2 Due Friday, 02/03/12 Last Name:___________________________________ First Name _______________ Workshop time or section:___________________TA name or Room # ___________ Please submit your homework on this sheet. If you need more space than is available, please attach additional sheets of paper. 1. Each of the displacement vectors A and B shown below has a magnitude of 3 m. i. Find graphically: (a) A + B (b) A - B (c) B - A (d) A – 2 B ii. In addition to the problem as given in the text, write down the x and y components of vectors A and B , and find components of the resultant vector in each part obtained by algebraic calculation. Check consistency of the values of these components with the resultant vectors obtained graphically. A x = B x = A y = B y = (a) (b) (A+B) x = (A-B) x = (A+B) y = (A-B) y = (c) (d) (B-A) x = (A-2B) x = (B-A) y = (A-2B) y = y B 3 A 3 30 0 x y B 3 A 3 30 0 x y B 3 A 3 30 0 x y B 3 A 3 30 0 x
