I came across a question on a past paper involving lifts and contact forces:
I've tried looking at the mark scheme and examiner report to understand the answer but I can't figure it out. I don't really understand what the mark scheme is saying so I'd appreciate somebody explaining how to properly answer this question and explain the physics behind it. Thanks in advance.
