(1 point) A man wishes to row the shortest possible distance from north to south across a river which is flowing at 5 km/hr from the east. He can row at 6 km/hr.

(a) In which direction should he steer? At an angle (in degrees) _________ east of south.

b) Suppose that when the man is in the middle of the river, a wind of 15 km/hr from the southwest starts. In which direction should he steer to move straight across the river? At an angle (in degrees) of ___________ west of south.

Canadian geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. One such bird is flying at 100 km/h relative to the air, but there is a 30.0 km/h wind blowing from west to east. PART A : At what angle relative to the north-south direction should this bird head so that it will be traveling directly southward relative to the ground? PART B: How long...

An athlete needs to get across a river. He must reach from point A on one bank to point B, which is directly across from point A on the opposite bank. If he wishes to minimize the total time T it would take to do so, at what angle upstreams (measured from the line AB) should he swim? Let his swimming/rowing speed relative to the water be 6.0 mi/h, and his running speed along the bank be 10 mi/h. The...

Jerome and Paul are competitive brothers. They live on a small farm on the northern bank of a river that runs purely east and west and that flows to the east at a rate of 1.200 m/s .   The brothers like to visit their Uncle Leo who lives on the southern bank of the river. The river is wide at this point, 1410.0 m across, and their uncle's dock is 205.0 m to the east of the point which is...
