Concept #1: Intro to Relative Motion (Relative Velocity)

Concept #2: Solving Relative Velocity Problems in 1D

Practice: A boat on a river is traveling from a pier to a point 500 m upstream (against the river’s current). The current flows at 4 m/s. If the boat makes the trip in 250 s, what is the speed of the boat relative to the water?

Example #1: City B lies directly east of city A. Without any wind, an airliner makes the 2775-km flight between them in 3.30h. If a steady 225-km/h wind blows from west to east and the airliner has the same speed relative to the air as before, how long will the trip from A to B take?
A) 7.1 hrs
B) 2.6 hrs
C) 9.0 hrs
D) 5.2 hrs
