Hey there forum! 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=-bυ2. But I cannot derive the equation P=Fυ from my equations. Thanks in advance!
