<a href="https://www.youtube.com/watch?v=FwGA8zb_CWM&t=154">2:34</a> If you are also lost in the signs thing... I was lost too.<br> So we have F= -mg - k(a v that as a vector points down).

if the positive is gravitation direction, how it can be negative too?😩

I dont understand how you got from a first-order differential to a function of u (Basically I dont get where the exponential has come from)

where did the other m go when sepparating variables
@reeb3687 · 2 years ago
I had a similar question on a physics test I took, in which I ended up with velocity on one side and an integral with velocity in it on another side. How might I go about solving this? I believe it was something like: initial velocity - k(integral from 0 to t of v dt) = v, the -k coming from a constant applied force -kv, and the initial and end velocities derived from the kinetic energy equation.

but how can air be negative , it is directing towards positive direction?

I didnt understand why and how you multiplied e^(kt/m)? You seem to have skipped a few steps...Pls help its urgent
