explain how

Expert Answer:

Dear Student
Swift movement along a zig zag path corresponds to changes in velocity and momentum of the hare  after every short interval of time.
This will require the dog that is chasing it, to undertake similar changes in its momentum after every short interval of time.
 
That is a challenge posed to the dog by the hare.
For every change in momentum requires a force to be applied by the dog, in teh direction of change in momentum.
 
We hope that clarifies your query.
