A sailboat moving in the direction shown is tacking to windward against a north wind. The log registers a hull speed of 5.1 knots. A "telltale" (light string tied to the rigging) indicates that the direction of the apparent wind is 31° from the centerline of the boat. What is the true wind velocity vw? Answer: Vw Uw 44° 31° knots 5.1 knots

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?
An airplane is flying at a heading S 75° W at a speed of 230 miles per hour relative to the air. The wind is blowing N 70° W with a speed of 35 miles per hour. What is the plane's actual velocity; that is, what is its speed and direction relative to the ground?

ere to search The Lost Drone. You and your team are exploring the edge of an Antarctic mountain range and you send a drone ahead to help navigate. After takeoff you lose sight of the drone and, a few seconds later, the controls malfunction and the drone stops sending visual images and navigational information except for speed and directional data. Changing speeds erratically, the drone heads west until it makes a drastic turn at the 5-minute mark to ß-35° east of south. After nearly ten minutes, the speed drops to zero and the drone stops sending data. It has crashed. Using the speed/directional data, the team draws up the graph shown below. (a) How far is the drone from you? (b) In what direction must you go to retrieve it?
