Unformatted text preview: 14 For each of the vectors in the first diagram, give the sign of the x and y components. Sign of x-component Sign of y-component r V 1 r V 2 r V 3 r V 4 r V 5 Suppose r A = 5 cm at 30 ° and r B = 8 cm at 150 ° . (a) Draw the vectors on the grid. (b) Sketch the sum r S = r A + r B of the two vectors. (c) Find the components of each vector. (d) Find components of the vector sum. (e) Find the magnitude and direction of the sum. x y 15 Measuring 3-D Vectors In this activity we’ll construct real position vectors to various points in the room and then determine the displacement vectors between each pair of points. Each table group will split as evenly as possible into two teams, “A” and “B” and each team will need to measure the components of two position vectors and determine a corresponding displacement vector. Set up Scattered around the room are 14 Post-it notes labeled 1A, 1B, 2A… etc. These represent the points for which we will find position vectors. Point 1A “belongs” to team A from table 1 etc. We will use a co-which we will find position vectors....
