How do I make a swinging elastic rope

I'm trying to do a swinging elastic rope for a platform game, on a sprite with either physics or platform behavior, & drawn simply as a straight line - no segmented physics joints.

The swinging will be used to perform jumps etc, so momentum is important. I don't want a perfect circular pendulum motion.

I'm new to programming & terrible at maths, so could use some ideas about where to start with this (although I suspect it should be with a highschool maths or physics textbook). I've attached one of my failed attempts below, which gives a rough idea of the motion i'm after...
