The figure below shows a system of two masses connected by a string. As m falls a
distance h, M accelerates up the plane. The coefficient of friction between M and the
inclined plane is µ.
What is the change in potential energy on the system after the m has fallen a distance h?

Best ResponseYou've already chosen the best response.0well. tension would cancel out :)

Best ResponseYou've already chosen the best response.0but definitely you need to use that formula I think this problem would be more approachable if we just considered doing it in terms of potential energy
