1. Create a force diagram of a car as it moves along a track?
2. Create a force diagram of mass hanger as it moves towards the ground?
3. Create a force diagram of a system car and mass hanger as they move together?
4. How does the acceleration of the car compare to the acceleration of the mass hanger? justify your answer.
5. What causes the system to accelerate?
6. Do you expect the acceleration of your system to be smaller than, greater than or equal to the acceleration due to gravity? Justify your answer.
7.Using newtons second law and the diagram you created in question #3, give the acceleration of the system as a function of the masses of the cart and the hanger.
