think about it right: the ball has two components of velocity, one that is tangential to the curve's surface and another that goes up or down the curve vertically. the up/down velocity isnt going to induce centripetal force off the wall bc its not in circular motion, only the horizontal...
its a dumb question. speaking VERY specifically youd be right bc the ball is further away from earth's centre at the top therefore less grav force... thats where i had to choose b/w d and a, i said a
i feel good enough rn too
made quite a few mc silly mistakes (3-4 im guessing at least) but apart from that i may have lost 2-4 marks in the rest of the paper, it felt good and i had time to take a piss after too
