a = 5 / (3s^(1/3) + s^(5/2))
I don't know if I can do partial fractions on this one, or maybe I'm just doing it wrong.

Gee, we don't know, either.

Always use the HW template when posting in the HW forums. Fill it out completely and be sure to include your work.

What is 's'?
 
Are you saying that the problem is to integrate [itex]\int\frac{5}{3s^{1/3}+ s^{5/2}}ds[/itex]?

Maybe you are doing it wrong. If you had included the complete problem statement, we might have a better idea about where you might have gone astray.
 
Hint: vdv = ads

That depends on what "s" means. I asked the OP about that but have received no reply. Is s = time? Is s = distance? It makes a genuine difference to the solution.
 
Yes, you're right Ray.
 
I imagine we have to read the rest of the problem from the stars and tarot cards.
