A river 108.6 m wide flows toward the south at 30.4 m/min. A girl on the west bank wishes to reach the east bank in the least possible time. She can swim 108.6 m in still water in 1.60 min.

(c) What is her velocity relative to land?

magnitude

direction ______ south of east

(d) What is the total distance she travels?

1. A certain sea cow can paddle 2.0 m/s in still water. If she attempts to cross a river, from the south bank to the north with a current of 3.0 m/s flowing toward the east by paddling entirely perpendicularly to the flow of the river, in what direction will she be traveling relative to an observer on shore? A. 12 degrees east of north B. 49 degrees west of south C. due east D. due north E. 34 degrees...

Thomas and Ashley are swimming in a river which is 15 m wide. Both swim with a speed u = 1.2 m/s relative to the water, which is flowing downstream at a speed v = 0.25 m/s. They both leave a point on one bank at the same time. Thomas swims directly upstream a distance 15 m, then turns back and swims downstream to his starting point. Ashley points herself so that, taking account of the current, she can swim...

A ferryboat, whose speed in still water is 4.00 m/s, must cross a river whose current is 3.00 m/s. The river runs from West to East and the boat is pointed North. a) If the boat does not compensate for the flow of the river water, and allows itself to be pushed off course, what would be the new velocity of the boat? In answering this question, draw a vector diagram with the appropriate labels for the vectors, and state...

A treasure map instructs you to walk (25.0+A) m south, followed by (18.0+B) m east, then 64.5 m north, and finally 28.5 m east. Determine the magnitude of your total displacement, if you follow these instructions. Calculate the answer in meters (m) and rounded to three significant figures. A=8 B=68 A boat traveling at (7.50+A) m/s relative to the water aims to go straight across a river. If the river is (54.0+B) m wide and the current in the river...
