I am having a lot of trouble with a lab problem where a hanging mass is attached via a pulley to a cart, the friction is assumed negligible as the cart is on an air track. The cart is released and the hanging mass drops, pulling the cart along. I can't seem to find the right equations to include the cart into the system and compare the kinetic energy to the potential energy.
For the kinetic energy part I am using this equation:[tex]Ke= \frac{1}{2}(m_1 + m_2)V^2[/tex]
