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.

Best ResponseYou've already chosen the best response.0And 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.

Best ResponseYou've already chosen the best response.1Sorry 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.
