Chapter 4.2, Problem 2bT

Obtain two spools and a ring stand. Use the equipment to check your predictions. (Be sure the thread of spool A is vertical before the spools are released.)

1. How does the magnitude of the acceleration of the center of mass $\left({\stackrel{\to }{a}}_{\text{cm}}\right)$ of spool A compare to that of spool B? Is this consistent with your free-body diagrams? Explain.

2. How does the direction of the acceleration of the center of mass $\left({\stackrel{\to }{a}}_{\text{cm}}\right)$ of spool A compare to that of spool B? Is this consistent with your free-body diagrams? Explain.
