Partners: __________________________________________________________ Physics 1112, Spring 2009 1 Cooperative Problems 2: Vectors and 2-D Motion 1. What can you say about the two vectors a G and b G in each of the following cases? For each case, draw a picture of the vectors, being as accurate and specific as the facts allow you to be. (a) c b a G G G = + and c b a = + . (b) b a b a G G G G = + . (c) c b a G G G = + and 2 2 2 c b a = + . (d) c b a G G G = and 2 2 2 c b a = + . 2. A car drives at constant speed in a clockwise sense around a level (horizontal) track as shown. (a) Draw the velocity vector of the car at each of points A, B, C, and D. (b) Draw a vector that represents the change in velocity between point B and point C ( Δ v G = v G C v G B ). (c) Indicate places on the track where the car’s acceleration is zero. (d) Indicate the places where the car’s acceleration has its maximum magnitude.
