For non conservative force, isn’t tension one of them ?

Can you do more wep questions with them giving you the co efficient knetic friction

[zhongxina]

A question, I always put the Wnet part in factorised form firstly by taking a direction as positive, example "(Force + Gravity -Friction) X displacement X cos(0)", this seems to work nicely, but my exposure to the topic regarding question papers is still a bit low, is there a chance this method can go wrong?

Hey Kev, I'm sorry but why did you put Fg // as positive since it was in the oposite direction?

[PRSEIMELA]

I'm confused I thought I had to also indicate the tension in the rope
