I also had argued for A in question 20, and saw that Matrix Education put D.

Prior to that, attempting to verify with a different method, I had tried to solve it using the Lagrangian method (I used sections 6.1 and 6.3 of

David Morin's book) and it seems to confirm A.

You're actually mental. Why r u doing Morin's book?

Also thought wise, by tilting stuff, without resolving, I'm pretty sure A checks out.

if interested, you could also possibly try Hamiltonianing it. I would suppose that works.

Re tilting, how does that work? Pretty certain the path is not in a plane.
If you pass a plane at an angle through a cylinder and unwrap the cylinder you get a sinusoidal curve, not a parabola.

lol just realised that my reasoning was wrong in a few bits.

path is not in a plane.
