1. The problem statement
I find it sometimes difficult to come up with the equation relevant to the question. If anyone has any tips, your help is appreciated.
2. Relevant example
For example:
A passenger climbs aboard a northbound bus and walks toward the back at a rate of 1.8m/s. The bus starts off up the street at 9.2m/s. What velocity will the passenger appear to be walking relative to:
A) a person who is walking 2.1 m/s south along the sidewalk
B) a person who is walking 2.1 m/s north along the sidewalk
Let p = passenger in the bus
b = Bus
g = guy who is walking
My attempt: a) Vpg = Vpb + Vbg is this correct? why or why not? thanks.
