a float boat originally leaves an island heading east at 100 km/h. Thirty minutes into the flight a storm blows, with winds from 30 degree south of east at 70.0 km/h blows the plane off course. After two more hours, the plane is forced to land. Where should the pilot instruct the rescuer to looks and what is the total displacement of the plane?

In searching for a boat lost at sea, a Coast Guard cutter leaves a port and travels 45.0 mi due east It then turns 35 north of east and travels another 45.0 mi, and finally turns another 35° toward the west and travels another 45.0 mi What is its displacement from the port? The distance from the port is 119 miles Round to the nearest mile as needed) The direction from the port is north of east Type your answer...
Two boats are heading away from shore. Boat 1 heads due north at a speed of 2.97 m/s relative to the shore. Relative to Boat 1, Boat 2 is moving 28.3° north of east at a speed of 1.66 m/s. A passenger on Boat 2 walks due east across the deck at a speed of 1.18 m/s relative to Boat 2. What is the speed of the passenger relative to the shore?
