- A boat whos speed in still water is 5.0m/s headed west across a river. The river current is 2.5m/s south. If the river is 2395 wide, how long does it take the boat to cross the river.I need help on this problem: A pipe discharges storm water into a creek. Water flows horizontally out of the pipe at 1.9m/s, and the end of the pipe is 3.5m above the creek. How far out from the end of the pipe is the point where the stream of water meets the creek? Express your answer with the appropriate units.A ship is on course for The Netherlands, heading North at 7.00 m/s. The ocean current is moving at 1.50 m/s in a direction of 40.0 degrees NE. What is the resultant velocity of the ship, and it's resultant direction?
- A river flows due south with a speed of2.0 m/s. You steer a motorboat across the river; your velocity relative tothe water is 4.2 m/s due east. The river is 500 m wide. What is your velocity (magnitude and direction) relative to the earth?A river is moving east at 4 m/s. A boat starts from the dock heading 30° north of west at 7 m/s. If the river is 1800 m wide, (a) what is the velocity of the boat with respect to Earth and (b) how long does it take the boat to cross the river?A kayaker needs to paddle north across a 100-mm-wide harbor. The tide is going out, creating a tidal current that flows to the east at 2.0 m/sm/s. The kayaker can paddle with a speed of 3.0 m/sm/s. In which direction should he paddle in order to travel straight across the harbor? How long will it take him to cross?
- A river is flowing at a rate of 7.62 m/s due South. You are canoeing across the river at a speed of 10.0 m/s, but want to make sure that your canoe travels due East, relative to the ground. What heading do you need to take, relative to the river? Express your answer as an angle, degrees North of East.A pipe discharges storm water into a creek. Water flows horizontally out of the pipe at 1.5 m/s, and the end of the pipe is 2.5 m above the creek. How far out from the end of the pipe is the point where the stream of water meets the creek?An airplane is flying northerly at a speed of 112 m/s when the wind blows towards 30.15 degrees south of the east at a speed of 25 m/s. what will be the resulting velocity of the airplane?
