**Physics**

okay so this is what i did to find the work done by overcoming friction: Ff = .9 N d = .91 m (Ff x d = Wf --> .9 x .91 = .82 J) hmm okay so how would you find the work done by friction using that calculation that you just said (change in total energy = work done by friction...

**Physics**

One way that I found was knowing the force overcoming friction (Ff). so the equation to fin dthe work would be Wf = Ff * d.. as you said above (force*distance). But what other calculation would you use to find the wasted work without knowing the friction force?
