A car of mass [tex]m_c[/tex] is connected to mass m2 by a string. The string passes over a solid cylindrical pulley, which has a frictionless bearing, of radius R and mass M. when the system is released from rest the string doesn't slip, the car moves down the incline, and m2 moves upward through a distance h' .

a) draw a free body diagram for [tex] m_c, m_2, and M [/tex]

b) Use the dynamical equations of motion to find the components of the net force aceting on [tex] m_c and m_2 [/tex] and net torque acting on M.

c) Use the results of b) to derive a expression for the translational aceleration for the masses in terms of [tex] m_c, m_2, M, h', 2[/tex] and the coefficient of friction [tex] \mu [/tex]

2. Relevant equations

dynamical equations ==> what is that exactly??

3. The attempt at a solution

a) a) draw a free body diagram for [tex] m_c, m_2, and M[/tex]

I drew it in with a picture of the drawing but I'm not sure the free body diagram of the pulley since I've never drawn a free body diagram of a pulley before. What forces would be on it other than that of the car and block?

b) b) Use the dynamical equations of motion to find the components of the net force aceting on [tex] m_c and m_2 [/tex] and net torque acting on M.I have no clue how to do this part at all.

What are the dynamical equations of motion???
