Swimming at 2.00 m/s relative to still water, a swimmer heads directly across a river of width 75 m. He arrives 40.0 m downstream from the point directly across the river from his starting point.

(a) What is the speed of the current in the river? (b) At what angle relative to the line perpendicular to the shore should he head to arrive at a point directly opposite his starting point?

Step 1

Step 2

(a) Calculating the velocity of the current of the river:

Step 3

(b) Calculating the angle at which the s...
