A swimmer capable of swimming at a speed of 10 ms in still, Ask an Expert

Academics

A swimmer, capable of swimming at a speed of 1.0 m/s in still water (i.e., the swimmer can swim with a speed of 1.0 m/s relative to the water), starts to swim directly across a 2.1-km-wide river. However, the current is 0.91 m/s, and it carries the swimmer downstream.

(a) How long does it take the swimmer to cross the river?

________s

(b) How far downstream will the swimmer be upon reaching the other side of the river?

______m
