A man can row at 1m/s when his boat is in fixed, stationary water.
In a river, water flows at 0,5m/s.
If the man tries to cross the river in which direction (angle with respect to the line that crosses the river) he needs to direct his boat to get to the opposite side of the river?
My answer is arcsin (1/sqrt(5)) which is 29,56°
Is that right?
Thanks
