In this video, I solve the AS Physics question from the October/November 2019 Paper 23, Question 4.
I highly recommend you watch this video, taking notes and doing calculations along with me. I explore the details, as the same principles can be applied to any question involving collisions in two dimensions.
This particular question is reminiscent of a playful scenario where two balls collide, roll together, and then hit and compress a spring.
I had lots of fun editing this video and hope you enjoy and learn something from it. Hasta la vista!
