1. The problem statement, all variables and given/known data Consider the following vectors: a = (5.0m) i + (2.0m) j b = (-14m) i + (6.0m)j Sum of a+b in unit vector notation? 2. Relevant equations 3. The attempt at a solution I'm not sure about this notation, all I know about adding vectors is graphically. Does (5.0m) i + (2.0m) j mean 5 meters in direction i and 2 in direction j?
