Thread: Parallel vectors.

I'm stuck with this question. I'm clueless as of this point.

Given A = 5i + j and B = 2i + kj where k is a scalar find k such that A and B are parallel.

2 vectors are parallel when they have the same direction.

This means A = cB (where c is a scalar).
Now can you setup the equations to solve for k?
