Question Video: Finding the Relative Velocity between Two Given Vectors Mathematics • First Year of Secondary School

Video Transcript

Given that the velocity vector 𝑉 𝐴 is equal to 17𝑖 and the velocity vector 𝑉 𝐵 is equal to eight 𝑖. Find the velocity vector 𝑉 𝐵𝐴.

We can calculate 𝑉 of 𝐵𝐴 by subtracting 𝑉 𝐴 from 𝑉 𝐵. In this case, we subtract the vector 17𝑖 from the vector eight 𝑖. Eight 𝑖 minus 17𝑖 is equal to negative nine 𝑖. This means that when 𝑉 𝐴 is equal 17𝑖 and 𝑉 𝐵 is equal to eight 𝑖, then 𝑉 of 𝐵𝐴 is equal to negative nine 𝑖.
