Find the unit vector that has the same direction as the vector below:
v= 4j
Need help solving and setting up thanks.

It has to have the same direction as this vector so it has to go in the j direction. Unit vector means its length is 1 so the answer is 1j or simply, j.

v = j.
Um... okay. The vector given goes directly in one direction from the origin. The unit vector has magnitude of 1. So, take a vector going directly in the same direction (straight positive on the j axis, with no i component) that has magnitude one.

j
since it is unit vector and has same direction

v = 4j = 4(0,1,0) therefore, the corresponding unit vector si: u = (0,1,0)
