A swimmer heads directly across a river, swimming at2.80 m/s relative to still water. He arrives at a point 49.0 m downstream from the point directly across the river, which is 73.0m wide.

Discover:

1. What is the speed of the river current?

2. What is the swimmer's speed relative to the shore?

3. In what direction must the swimmer head so as to arrive at the point directly opposite his starting point? Express your answer in terms of the angle by respect to a line drawn directly across the river.
