You are in a boat, and you need to cross the river. Your boat's motor can put out a steady speed of 12 m/s but there is a current at 4.0 m/s. You have two options: to aim upstream or downstream. Compare the distance, time, and ultimately velocity for each of your two options.

- Please as soon as possibleDavid is buying a jet boat this summer and spending a lot of time zooming around. One place he plans on going is to the Plate River above Albany, NY. The current is 4 m/s south and the river is 200m wide. the boat will move at 20 m/s at full throttle, his only setting. A. how quickly will he cross the river if he heads straight across?B. how far downstream will he end up if he does so?C. if he wants to go straight across, what angle upstream should he use?A rescue plane flies at 198km/hr and at a constant elevation of 500m toward a point directly over an accident victim struggling in the sea. The pilot must release a rescue capsule so that it hits the water very close to the victim.a). what should be the angle of the pilot’s line of sight when the capsule is released? EVb) what is the velocity of the rescue in the vertical plane when the capsule is released? APc). as the capsule reaches the water, what is its velocity ?̅in i. the unit vector notation? ANii. magnitude- angle notation
- Please refer to the question that is attached. The boat in the picture below is tring to travel north to cross the river at 10 m/s, however the water in the river is flowing west at 4.0 m/s. The boat instead angles itself to counteract the flow of the river. For this problem orient the coordinate axes with x pointing east and y pointing north. Question A: which of the following best represents the velocity of the water? 1. < 0, -4.0 > m/s 2. < 4.0, 0 > m/s 3. < 0, 4.0 > m/s 4. < -4.0, 0 > m/s Question B: Which of the following best represents the desired velocity of the boat? 1. < 0, 10.0 > m/s 2. < -10.0, 0 > m/s 3. < 10.0, 0 > m/s 4. < 0, -10.0 > m/s Question C: Which of the follwing best represents the adjusted velocity of the boat? 1. < -10.0, -4 > m/s 2. < 4, 10.0 > m/s…A river flows due east. A boat travels with constant speed due north across the river from point A to point B. The speed of the boat relative to the water is 5 m/s. The river is 21m wide and it takes 7s to travel from A to B. What is the speed of the current in the river?After a constant acceleration of 3.52 m/s/s at 9.6 degrees above the +x-axis is applied by the motors of a boat for 7.05 seconds, the boat is moving at 96.8 m/s at 34 degrees above the +x-axis. What was the displacement of the boat during this time? What is the angle from the positive x-axis?
- i push a cart up a 5 degree hill at 2m/s. what is my horizontal and my vertical velocity ?A keen physics student starts swimming on the south bank of a river and heads straight across. They can swim at 1.2 m/s. The current is flowing west at 2.0 m/s. Calculate the magnitude of the swimmers velocity relative to the ground. Input your answer with one decimal place, round accordingly.3. Sara can swim at a speed of 3.5 km/h in still water. She encounters a current of 1.25 km/h while trying to cross a river. What is her resultant velocity? Include a vector diagram and direction.
