A river is to be crossed by a girl using a row boat.
Assume that the water has uniform velocity, represented above by
the vector labeled H. The rowing speed of the girl and a set of
possible orientation of her boat are also shown. Select the
direction (i.e., F, or D, or ...) in order to cross the river in
the shortest time. (Notice that the number of tries is
reduced.)

URGENT A 400.0-m-wide river flows from west to east at 30.0 m/min. Your boat moves at 110 m/min relative to the water no matter which direction you point it. To cross this river, you start from a dock at point A on the south bank. There is a boat landing directly opposite at point B on the north bank, and also one at point C, 75.0 m downstream from B a)Where on the north shore will you land if you...
