Chapter 4, Problem 15SA

A simple pendulum as shown in ● Fig. 4.24 oscillates back and forth. Use the letter designations in the figure to identify the pendulum’s position(s) for the following conditions. (There may be more than one answer. Consider the pendulum to be ideal with no energy losses.)

1. (a) Position(s) of instantaneous rest ___
2. (b) Position(s) of maximum velocity ___
3. (c) Position(s) of maximum E_k ___
4. (d) Position(s) of maximum E_p ___
5. (e) Position(s) of minimum E_k ___
6. (f) Position(s) of minimum E_p ___
7. (g) Position(s) after which E_k increases ___
8. (h) Position(s) after which E_p increases ___
9. (i) Position(s) after which E_k decreases ___
10. (j) Position(s) after which E_p decreases ___
