I wish to know the work done by F ext1. Anyway, why would I want to know the force done by the constant force, when it is just W = Fd.

Sorry for not making this clear. There is forceext1 = k1v2 that is acting against the object and constant forceext2 = mk2 acting on the object.

Let me clarify, Fext = k1v2. Fnet = ma = mk2 - Fext.

Homework Statement Help. If w = ∫F dx where w is work, f is force and x is displacement, and also F = k1v2 where force is a quadratic function of velocity v times a constant k1, what would be work with regards to velocity? Homework Equations More info if needed. v = ∫a dt a = k2 - k1v2/m k2...
