Re: Displacement



Here is another question about dispalcement.

Suppose you exercise by walking for 15 minutes on a treadmill that has a
level track that moves at a velocity of -4km/hr.
Remembering that the treadmill belt is a rubberized loop that returns to its
original position after every full turn, what would be your total
displacement relative to the treadmill track when you are finished exercising
and you dismount off the belt from the same spot that you started your
exercise ?

Using the argument that dispalcement is final minus initial,
would your dispalcement then be 1 km or zero km ?
