Hey there forum!(adsbygoogle = window.adsbygoogle || []).push({});

Consider a damped oscillation in which the friction force is F=-bυ.

What I want to ask is how do you calculate the work done by this force for any x interval along a line and what is the Power of the work done by this force?

I already know that Power P of the work done due to a force F is P=Fυ, therefore substituting would give P=-bυ^{2}. But I cannot derive the equation P=Fυ from my equations.

Thanks in advance!
