What is the resultant velocity vector when you add your swimming velocity and the current velocity? give the x and y components in meters per second separated by a comma?

The resultant vector, is the vector that adds the components x and y separately.

Since the two x components are 0.00 m/s and 1.00 m/s, the resultant x component will be:

0.0 m/s + 1.00 m/s = 1.00 m/s in + x direction

Similarly, the y components will be:

-1.00 m/s + 0.00 m/s = - 1.00 m/s in - y direction

So, the resultant vector will be:

(1.00 m/s, - 1.00 m/s)
