5. An aeroplane intends to fly to a city that is 200 km due north of its current location. The plane can fly at 250 km/h in still air. A 100 km/h wind is blowing to the north west direction. The pilot forgets to take into account the wind and he heads due north. The pilot estimates his travel time without considering the wind. What is this time? Give your answer in hours. b) In what direction does the plane...

A model airplane competition has the following rules: Each plane must fly to a point 1 km from the start and then back again. The point km winner is the plane with the shortest round-trip time. The contestants are free to launch their planes in any direction, so long as the plane travels exactly 1 km out and then returns. On the day of the race, a steady wind blows from the north at 8.5 m/s. Your plane can maintain...

A light airplane attains an airspeed (speed of the plane with
respect to the air) of 500km/hr. The pilot sets out for a
destination 800km due north, but discovers that the plane must be
pointed 20.0◦ east of due north for the plane to reach there
directly (i.e., the nose/front of the plane is pointed 20.0◦ east
of due north, but the plane itself moves due north as seen by
someone on the ground). The plane arrives in 2.00hr. P,...

Background: Jerome and Paul are competitive brothers. They live on a small farm on the northern bank of a river that runs purely east and west and that flows to the east at a rate of 1.400 m/s . The brothers have run some time trials on the farm pond, and they know that, in still water, Jerome can paddle the family canoe at a steady rate of 2.950 m/s for a considerable length of time. When younger brother Paul runs a...
