How to do pole jumping physics?

Hi, I would like to make a pole stick just like in this game from the ps4 sportfriends: sportfriends

I am a still a beginner with around 40-50 hours of unity experience and developing for fun and done some time most in simple 2D development. But I have no clue on how to think or what components to use to make this work... I mean both graphic wise and physics.

All help och clues are appreciated that gives me on the right direction thx :)
