Sheena can row a boat at 3.20 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.80 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head upstream at an angle of 25.0° from the direction straight across the river. a.)How far upstream or downstream from her starting point will she reach the opposite bank? If upstream, enter a positive value and if downstream, enter a negative value. b.)In order to go straight across, what angle upstream should she have headed?

(b) The pilot maintains the planes original course, altitude, and speed through a storm of flak. Where is the plane when the bomb hits the ground? (c) The bomb hits the target seen in the telescopic bombsight at the moment of the bombs release. At what angle from the vertical was the bombsight set?
A small plane flies at 200 km/h in still air. If the wind blows directly out of the west at 50 km/h, (a) in what direction must the pilot head her plane to move directly north across land and (b) how long does it take her to reach a point 300 km directly north of her starting point?

Express your answer using two significant figures. B. How long will it take you to cross the river? Express your answer using two significant figures.
In an airplane that has an air speed of 250 mi/hr, a pilot wishes to fly due north. If there is a wind blowing at 60 mi/hr toward the east, (a) what should be the compass heading? (b) what will be the plane’s ground speed?
A dolphin wants to swim directly back to its home bay, which is 0.800 km due west. It can swim at a speed of 5.20 m/s relative to the water, but a uniform water current flows with speed 2.83 m/s in the southeast direction. A) What direction should the dolphin head? Enter the angle in degrees where positive indicates south of west and negative indicates north of west. (in degrees) B) How long does it take for the dolphin to swim the 0.800-km distance home? (In min)

On a winter morning a mailman drives 3.50 due east of the post office to deliver an express package to the school. He then walks due south to a coffee shop to meet a friend. If the magnitude of the mailman’s total displacement vector at the coffee shop with respect to the post office is 5.0km, A) how far south the mailman walked? B) what is the direction and angle of his total displacement vector while at the coffee store with respect to the post office?
A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 12 m/s. A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 16 m/s relative to the air, in what direction should they head in order to move directly south?
A duck with a still water velocity of 5.00 km/hr heads across a stream that flows directly West with a velocity of 3.00 km/hr. a) What must be the heading of the duck if it is to maintain a path directly South across the stream ? Draw a vector diagram along with your work. b) How long will it take the duck to cross the stream if the stream is 200.m wide and the duck maintains its heading ? (c) What will be the duck’s resultant velocity if it does not fight the current ? Draw a vector diagram along with your work. ) d) How long will it take the duck to reach the opposite side if it does not fight the current ? Remember, the stream is 200.m wide. e) How far downstream, relative to the bank, will the duck be carried if it does not fight the current ?
An SR-71 reconnaissance aircraft, the world's fastest aircraft, is flying east at 3000 km/h. a. If the plane encounters a crosswind of 300 km/h that is directed to the north, what is the magnitude and direction with resultant velocity? b. If the border lies along a straught north/south line, will it take the plane, more, less, or the same amount of time to reach the eastern border if there were no crosswind?
