A system is defined as two connected masses in an atwood machine and the earth. How do I find total kinetic energy in a system where more than one object is moving (or is only one object actually moving since the two masses are connected with a string? idk)
This is an isolated system so... ΔK...

Homework Statement
In the system below, m1<m2. When the object of mass m2 has descended a distance h, the potential energy of the system has decreased by:
Homework Equations
the answer is (m2-m1)gh
The Attempt at a Solution
I used ΔU= Uf-Ui
m1gh-m2gh=ΔU (I think that the decrease in...
