## IVP for v(t) and x(t)

Hi all,

I attached my questions. I think that I have a lot of good thoughts abut these, but I just cant pull them together.

One of the formulas in the text is, mv^{1}=-mg-kv so I tried to apply that and I came away with... 80v^{1}=-80*9.8-k(30) for question 1a

I don't know if there is a general equation to work from for all of these, or if it is specifc absed on the question. I am working out of the Differential Equations Labratory Workbook by Coleman and Boyce.

Any help would be great!

Thanks!
