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.

Canada 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 goose is flying at 100 km/h relative to the air but a 42 km/h wind is blowing from west to east. a) At what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground? b) How long will it take the goose to cover a ground distance of 550 km from north to south? (Note: Even on cloudy nights, many birds can navigate using the earth's magnetic field to fix the north-south direction.)
An airplane pilot wishes to fly directly westward. According to the weather bureau, a wind of 75.0 km/hourkm/hour is blowing southward. The speed of the plane relative to the air (called the "air speed") as measured by instruments aboard the plane is 310 km/hourkm/hour . In which direction should the pilot head? a)What is the speed of the air relative to a person standing on the ground, vA/G? What is the speed of the plane relative to the air, vP/A?
The Airbus A350 from Manila bound for St. Petersburg cannot travel in a straight route due to weather disturbances and some restrictions in the air space. Instead, it travelled at a velocity of 740 kph due 25° NNE, then it turned towards East at a velocity of 870 kph. After that, at a velocity of 900 kph, it ventured 35° WNW, then it turned 50° South of West maintaining the same velocity of 900 kph. Finally, to reach its destination, it needs to turn towards west at a velocity of 350 kph. Find the magnitude and direction of the resultant of the airplane’s velocity during its flight.
