Chapter 2.2, Problem 3bT
Draw and label a free-body diagram for system C.
Compare the forces that appear on your free-body diagrams for system C to those that appear on your diagrams for system A and B in section II.
For each of the forces that appear on your diagram for system C, list the corresponding force (or forces) on your diagrams for system A and B.
Are there any forces on your diagrams for system A and B that you did not list? If so, what characteristic do these forces have in common that none of the others share?
Why is it not necessary to consider these forces in determining the motion of system C?
Note that such forces are sometimes called internal forces, to be distinguished from external forces.

Draw a free-body diagram of the block in the space below. Label each force that you have included in your free-body diagram to indicate (1) the type of force, (2) the object on which the force is exerted, and (3) the object exerting the force.
The following exercises are designed to get you thinking about the concepts you will investigate in
the lab. It is not necessary for you to understand them all right here, only that you think carefully
about your ideas.
Exercise:
1) Two blocks at rest on a frictionless table are in contact as shown in the figure below.
B
Compare the force block A puts on block B (same, bigger, or smaller) to the force block
B puts on block A when:
a. they are pressed together and remain motionless. Explain.
b. they are pressed together and accelerating to the right. Explain.
c. they are pressed together and accelerating to the left. Explain.
The figure below shows a massless string wound around a spool of radius r. The mass falls with a constant acceleration, a. What is the equation for y in terms of θ and r? What is the equation for v in terms of ω and r? What is the equation for a in terms of α and r? Start from the expression for uniform acceleration in the y-direction for the falling mass and clearly show any steps or substitutions you make.
