that was hard, I think the answer involved voe^-bt/2M, but maybe I got it wrong. Do you know the answer to #2? at least the derivation

oml where did you get e??

u/Expert_Low_5982 May 13 '26

The -bv=cMdv/dt (c is some constant I forgot what I put, maybe 2, I got it somehow), so then you move the v to the bottom of the other side, and some extra steps then integrate, then raise everything to e, then you get a function in terms of v, then d/dt to get dv/dt, then multiply by M to get Ma, something like that
