Chapter 2.3, Problem 2aT

If the motion of the blocks is the same as in section I, how does the net force on the string compare to the net force on the rope?

1. Determine whether the net force on each of the objects is greater than, less than, or equal to the net force on the object in section I. Explain.

• block A
• block B
• the system composed of the blocks and the connecting rope or string

2. Compare the horizontal components of the following pairs of forces:

• the forces on the string by block A and the rope by block A. Explain.
• the forces on the string by block B and the rope by block B. Explain.
