swimmer who achieves a speed of 0.75 m/s in still water swims directly across a river 72 m wide. The swimmer lands on the far shore at a position 54 m downstream from the starting point. (a) Determine the speed of the river current. (b) Determine the swimmer’s velocity relative to the shore. (c) Determine the direction the swimmer would have to aim to land directly across from the starting position.
