1. The problem statement, all variables and given/known data Vector V1 is 6.4 units long and points along the negative x axis. Vector V2 is 8.9 units long and points at 60 degrees to the positive x axis 1) find x and y components of v1 and v2? 2) find magnitude of the sum v1+v2? 3) find the angle of the sum v1+v2? 2. Relevant equations 3. The attempt at a solution I found the answers to part 1 (v1= -6.4,0 and v2= 4.5,7.7) and part 2 (8.0) but need help with part 3. thanks!
