Homework Help: physics

Posted by Ashley on Tuesday, September 11, 2012 at 3:19pm.

A swimmer heads directly across a river, swimming at 1.10 m/s relative to the water. She arrives at a point 52.0 m downstream from the point directly across the river, 72.0 m wide. What is the speed of the river current? What is the swimmer's speed relative to the shore? In what direction (as an angle relative to a direct line across the river) should the swimmer aim instead, so that she arrives at the point directly opposite her starting point?
