93.35 :) Way higher than what I was headed for near the start of the year. Got guaranteed entry into my first pref, UNSW CompSci, so I'm completely happy.

but how would it go back to the initial velocity if there is nothing to accelerate it after its been slowed down by the magnet?

yeah doesn't it go down the whole time, i also accounted for a slight amount of friction so it is decreasing at different rates the whole time. lots of others didn't apparently but i explained it in the explanation and also started the line from v so it should be OK.

Damn... usually they look for marks to give though so hopefully they wont take away more than one.. looking at 88-93 raw then..

Omg, I didn't see for 16b that they wanted volume to 1dp, my answer is correct but its in exact form :/ Will I get 2/3 because of that?
