Tricky incline problem

  1. Jan 20, 2005 #1
    Question is:

    A wedge makes an angle theta to the horizontal. it has a mass M2 and can slide along the horizontal. A mass M1 slides along the frictionless surface of the incline. What are the expressions for the acceleration of the wedge and the mass M1?

    I am just puzzled. Any suggestions to get me started is great.

    1. What happens to the wedge as the mass on it moves down the incline?

    2. Can you draw a freebody diagram to see the interplay of forces?

    3. Apart from forces, what approach can you think of to solve this problem? What are the constraints of the system? What are its dynamic variables?
