Chapter 11, Problem 42P
A simple pendulum in a science museum entry hall is 3.50 m long, has a 1.25 kg bob at its lower end, and swings with an amplitude of 11.0°. How much time does the pendulum take to swing from its extreme right side to its extreme left side?

A simple pendulum has a period of 3.5 s and an amplitude of 5.0 cm. The mass of the bob is 5 g. Calculate the maximum kinetic energy of the pendulum and give your answer micro Joules (μJ).
This, the length of the pendulum is 2.08 m. Now you start with the pendulum at 13.8 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 34.5 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it?
2.68 m/s
1.09 m/s
3.75 m/s
2.45 m/s
This, the length of the pendulum is 2.46 m. Now you start with the pendulum at 18.2 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 30.3 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it?
