Exactly this is why I used Extension 2 since I saw Integrand do it once and it actually workedRIP for that copper question.
I drew a straight line with negative gradient and then from C to D it was FAIRLY straight (but not exactly).
lol. at least my explanation was alright, maybe 2/5 lol.
Mechanics helped me alot for physics... Mainly resistance questions...Biggest regret: Dropping 4u. Should've kept it just for physics.
was this the mechanics topic where you learnt this..because that is the ONLY 4u topic i didn;t learn.
or was it the 4u integration topic ---> because i already know 4u integration so if i could have used it i'm such a dickhead for not using it.
Okay this was my reasoning for my graph:Okay haha thought so, thanks

Okay this was my reasoning for my graph:
I said as eddy currents are induced on the copper plate, causing it to slow down.
but then, the trolley passes through the magnet, and the direction of the eddy currents are then switched, causing it to experience a force in the opposite direction (i.e. accelerating it to the right slightly).
Where did I go wrong?
if i explained all the shit correctly with CORRECT REASONING (i did) but drew the graph that i did (negative straight line from A to C, and then a fairly straight line from C to D), can i get 2/3 out of 5???As it leaves it is also slowed down remember how a similar experiment where a magnet dropped through a metal induces an m field to always slow down the magnet whether it enters or leaves.
I think so. Also the question would've been more amazing if there was friction from the floor aswell... But since V didnt change there was no friction...if i explained all the shit correctly with CORRECT REASONING (i did) but drew the graph that i did (negative straight line from A to C, and then a fairly straight line from C to D), can i get 2/3 out of 5???
