Physics toughness

So I'm studying for the AP physics exam on monday. Man there's some tough stuff.

Anyway one of the physics open response problems is
There's a block moving at initial velocity Vo
There's a force opposing the block's motion at F = -kv
There is no friction

And it asks for an equation for velocity in terms of time.

And I'm completely stuck on it. I can get velocity in terms of position and such, but I just can't seem to figure out how to calculate it in terms of time.

It also asks you to graph the function, which I was able to do cause I know what it should look like (start at Vo and trails off to 0 at infinity)

So I know it's probably some inverse exponential function, I just don't know how to derive it.

If you're old enough to get off your tits on crack, you're old enough to die for it. It sucks that he's dead, but he was well old enough to know what he was getting himself into.

dELta to the rescue

F = -kv
a = -kv/m = dv/dt

dt/dv = -m/kv
t = -m/k * ln v
v = e^-kt/m

forgot about constant in integration :P silly me

v = C + e^-kt/m
t = 0, v = C + 1
C = Vo - 1

v = Vo - 1 + e^-kt/m

I think we once had a thread called 'Show NG what you're working on', I can't seem to find it right now. There's always the Showcase Thread though.

Also, I almost accidentally posted a link to pr0n instead of a link to the showcase thread, now that would've been embarrassing. Heat + alcohol does not positively effect my mental capabilities.
