Relative Motion
Relative velocity of a passenger on a train with respect to a person on the ground.
Problem
Suppose the passenger on the train is climbing
a vertical ladder with a speed of 
and
the train is slowly coasting forward at 
.
Find the speed and direction of the passenger relative to the ground.
Problem
You are riding in a boat going 
at
an angle of 25¾ upstream on a river flowing at 
.
What is your velocity relative to the ground?
Problem:
In the figure a bat detects an insect (lunch)
while the two are flying. The bat has velocity 
relative
to the ground, and the insect has velocity 
relative
to the ground. What is the velocity 
of
the insect relative to the bat, in unit-vector notation and as a magnitude
and an angle?
