Question

The components of a vector V areoften written (Vx, Vy, Vz). Whatis the y component of a vector which is the sum of the two vectors,V1 and V2,whose components are (2.93, 2.14, 0.00) and(3.46,     -3.45, -2.43)? Calculate the length of this vector. In class our teacher told us to add v1 to v2 (2.93+3.46),square them, and then sq root. it..I got 6.95 but my answer iswrong... The components of a vector V areoften written (Vx, Vy, Vz).

Explanation / Answer

Given vectors :          Let V1 = 2.93 i + 2.14 j+ 0.00 k                V2  =   3.46 i - 3.45 j - 2.43 k V1 +   V2     = 6.39 i   - 1.31 j - 2.43   k Now Lenght of the given vectors is:                                      ( 6.39)2   + ( - 1.31)2 + ( - 2.43)2   = 6.960 ˜ 7 m Hope this helps u!
