Two blocks (with masses 20.5 kg and 68 kg) are connected by a string as shown. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block and machine is 0.257. Find the change in the kinetic energy of the block on the incline as it moves a distance of 15.4 m up the incline if the system starts from rest.

    first, I have to set up equation for sum of force, find net force, then multiply it by the distance, right?

    you can't cheat, this has to be stopped. Ask this question out of your knowledge of theory.

    And my theory is apparently wrong, and I don't know why. And it's isn't cheating. You are obviously trolling, just like Yahoo! said.

    Sorry to interrupt. I think it's better to stop the discussion on cheating here. And also, it's okay to seek help for your homework, as long as you're looking for a way to learn how to do it, not just copying others work. @ndwelsh I think we'd better have a private talk.

    what is fun about substituting numbers to formulas? Aren't you striving for better degree? What are you supposed to learn? Physics, elementary principles of expressions and variables?

    Yet, I don't need you, fortunately. There are knowledgable beings who are wise enough not to troll in this site and are willing to help others. What about you? Answer now. What do you do with your life? Trolling? Well, that's pathetically sad. Beside you are wasting your time.
