The figure shows a red row boat (the dot) that needs to cross a river. The boat can be rowed with an average constant speed of 6 ft/s in still water. Let W = 40 ft, d = 30 ft, and v = 2 ft/s (the constant river speed). N W / IE h d N B | U. Figure 10.2: CrossRiver.png (a) If the boat begins at A and must make landfall landfall at point B, what angle should the boat be pointed and how long will it take to cross? Solution lies between (19.688, 6.444) and (23.112, 7.5896) (b) If the rower thinks there may be dangerous creatures in the stream that might capsize the boat, she wants to make landfall as quickly as possible and doesn't care where that is. What angle should she point the boat and how long will it take to cross?Solution lies between (-0.12, 6.0003) and (0.1, 7.00035)

A plane that is capable of travelling at 140 m/s wishes to travel due north from City A to City B, 500 km away, but encounters a constant crosswind that blows 25 m/s due west. What must the plane’s heading be in order to reach its destination? Suppose the pilot has no navigational expertise and decides to aim straight for City B. How far west of City B will the plane end up?
A firefighter, a distance d from a burning building, directs a stream of water from a fire hose at angle i above the horizontal as shown in Figure P3.16. If the initial speed of the stream is vi, at what height h does the water strike the building? Figure P3.16
A jetliner with an airspeed of 1000 km/hr sets out on a 1500 km flight due south. To maintain a southward direction, however, the plane must be pointed fifteen degrees west of south. If the flight takes 100 min, what is the wind velocity?
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 cannon ball was fired at 20m/s. If it was launched at 30 degrees above the horizontal, find (a) the components of the velocity, (b) maximum height, (c) total time of flight, (d) range and (c) the final velocity before it hits the ground.
A field biologist is studying the migration patterns of northern gannets (a type of seabird). On one particularday, she records that they fly 5.0 km northeast, then turn toward to the south of east by 30 degrees and fly 4.0 kmin the new direction. How far north or south of their original position are the birds?
3.15. .. An airplane is heading due south at a speed of 590 km/h . If a wind begins blowing from the southwest at a speed of 60.0 km/h (average).
the leprechaun in the shamrock patch was named O'Malley and since he was disrupted from sitting in his patch he decided to go off and play a round of his favorite sport in where leprechaun kick a gold coin from a tee into a post 317m away. if he kicked the coin at an angleof 60 degree at a velocity of 60 m/s how high was the arch of the rainbow created by the trajectory? how long did it take to get to the pot?
A car travels at a constant velocity of 80.0km/hr for 45.0 minutes. If the direction of the motion is 60.0o S of W, what is the vertical and horizontal components of the displacement ?
A rugby player passes the ball 9.75 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? (Answer in Degrees) What other angle gives the same range? (Answer in Degrees) For the pass using the smaller of the two angles, how long is the ball in the air? (answer in Seconds)

(a) Find the components of the velocity of the jet airliner relative to the air, JA. vJA,x = mi/h vJA,y = mi/h (b) Find the components of the velocity of the air relative to Earth, AE. vAE,x = mi/h vAE,y = mi/h (c) Write an equation analogous to vAB = vAE − vBE for the velocities vJA, vAE, and vJE . (In the given equation, vBE is the velocity of observer B relative to observer E. Object A travels with velocity vAB relative to observer B, and velocity vAE relative to observer E.) vJA = vJA = vAE + 2vJE vJA = vAE − vJE vJA = vJE − vAE vJA = vJE + vAE (d) What are the speed and direction of the aircraft relative to the ground? magnitude mi/h direction ° north of east
