Some problems in Mastering Physics require answers in the form of a single vector or an expression involving multiple vectors. This problem will show you how to enter vector answers in MasteringPhysics Throughout the problem refer to (Figues 1), which shows a Figure 1 of 1 Component notation One common way of expressing vectors is in terms of their components For example, the x component of A writton A, is equal to 2.5 (since that is its length along the x axis) Likewise, they component of A written A, is 3 You can express a vector in terms of its coordinates as follows A-(A.. 4,)-(2.5,3) What this means is that if the tail of the vector A is at the origin, then its sp is at the coordinates (2, 3)-(2.5,3) When a problem in MasteringPhysics requires a vector answer in component form, the answer instructions will typically read something like Enter your answer as a pair of vector components, separated by a comma." In this case you would enter your answer to the above scenario as 2.5.1 The surrounding parentheses should not be entered - Part A Using component notation, enter the vector in the answer box Enter your answer as a pair of vector components, separated by a comma. You should not enter any parentheses.

This problem will show you how to enter vector answers in MasteringPhysics Throughout the problem, refer to (Figure 1), which shows a Figure y axis Unit vectors As the name suggests, unit vectors are vectors of unit length (1). It is common and often convenient to write vectors in terms of a unit vector in the r direction (a) and a unit vector in the y direction (4) In three dimensions, there is an additional unit vector in the z direction (2) Some textbooks use the unit vectors . J. and A in place of 2 y. and i respectively For example, you can express the vector A in terms of unit vectors as follows A-25 +3 When a problem in MasteringPhysics requires a vector answer in terms of unit vectors, the answer instructions will typically read something like Enter your answer in terms of the unit vectors and y Part B How would you express using unit vectors?
