Physics Trello Tasks

Hi there, this task on the Physics section in Trello is marked for being completed in September, however looking through both the 4.9 and Master branches of the Github repo lead me to believe that it hasn’t been started yet.

Is it still on track, or has it fallen by the wayside?

There is enough detail that another developer such as myself could probably implement and test in relatively quickly, (and it would be very useful for a private project I want to work on)… if I were to do this, which github branch would be the preferred one to work from? I would guess the Master branch would be the one to submit a Pull Request to?

Edit: Sorry, just realised this should be in the Engine Source section. Please move this.
