Suppose that you are swimming in a river while a friend watches from the shore. in calm water, you swim at a speed of 1.25 m/s . the river has a current that runs at a speed of 1.00 m/s. note that speed is the magnitude of the velocity vector. the velocity vector tells you both how fast something is moving and in which direction it is moving. if you are swimming upstream (i. a., against the current), at what speed does your friend on the shore see you moving?
