I should be able to do this problem, but for the life of me I am lost in what is probably an easy integral.

I have a = dv/dt = g-kv

The hint was to do a U substitution for g-kv, no problem.

I am lost because of the two =, I just don't know hopw to set up the problem to get v=(g/k)(1-e^-kt).

Thanks in advance.

Just ignore the "a=". It's part of the definition, not part of the equation. ;)

Thanks.
