Hey guys! I am back for a second time. (Woo) More Awesome Physics underway! 1. The problem statement, all variables and given/known data The components of a vector V are often written (Vx, Vy, Vz). What are the components and length of a vector which is the sum of the two vectors, V1 and V2, whose components are (3.4, 1.0, 15.0) and (5.1, -4.6, -1.0)? 2. Relevant equations (Vx)=8.5 (Vy)=-3.6 (Vz)=14 3. The attempt at a solution To my understanding it should be (Vx)² + (Vy)² + (Vz)² = √Length But my Program say nay to such an answer...Is there somthing I missed?
