A river flows due south with a speed of 4.00 m/s. A man steers a motorboat across the river; his velocity relative to the water is 3.80 m/s due east. The river is 790 m wide. How much time is required for the man to cross the river? (Express your answer in seconds.) How far south of his starting point will he reach the opposite bank? (Express your answer in meters.)

A helicopter leaves its base and travels 20.0 km north. After a brief stop, it flies 35.7 km south, pauses briefly and then flies 17.0 km north. Finally, it flies 6.0 km south and lands. At the end of the trip, what is the displacement of the helicopter from its base?
A projectile is shot with a speed of 15.3 m/s at an upward angle of 69.9° from the top of a cliff 22.5 m high. How long does it take the projectile to hit the ground? Express your answer in seconds to 3 significant figures. Use g=9.81 m/s2.
I have no idea to how to start to this question: Wags (a dog) decides to go on a journey. He begins his journey by traveling 58 meters in a direction directly south. He then runs 100.0 meters in a direction 30◦north of west. During the last leg of his journey, he follows a scent for 59 meters in a direction 30◦east of north. What distance does Wags end up from his initial startingpoint?
A river 109.5 m wide flows toward the south at 35.0 m/min. A girl on the west bank wishes to reach the east bank in the least possible time. She can swim 109.5 m in still water in 1.10min. How long does it take her to cross the river? Also how far downstream does she travel? What is her velocity relative to land?find the magnitude and direction south of east? Also what is the total distance she traveled? And last in what direction must she swim if she wishes to travel straight across the river?
In a time of 2.67 h, a bird flies a distance of 86.7 km in a direction 30.2 degrees east of north. Take north to be the positive y direction and east to be the positive x direction. Express your answers in km/h. What is the x component of the bird’s average velocity? What is the y component of the bird’s average velocity?
A North American river otter wants to cross the North Saskatchewan river. It can swim at a speed of 2.75 m/s. In that location, the distance directly across the river is 45.0 m. a) How much time does the otter take to get to the other side, if it points directly across the river? b) If the current velocity is 2.5 m/s, how many metres downstream will the current have carried the otter when it gets to the other side? c) Using the same velocity, calculate the otter's velocity, relative to the bank from where it started.

A swimmer who can consistently keep the same pace to cover 50 meters in 7.71 seconds sets out to swim across a river. The current in the river moves at 3.31 meters per second as the swimmer keeps a constant pace trying to get directly across (at a right angle to the current). What is the actual speed of the swimmer compared to land? (Your answer should be in meters per second,
