A simple pendulum is swinging back and forth through a small angle, its motion repeating every 1.29 s. How much longer should the pendulum be made in order to increase its period by 0.12 s?

A pendulum is formed by pivoting a long thin rod about a point on the rod. In a series of experiments, the period is measured as a function of the distance d between the pivot point and the rod's center. (a) If the rod's length is L = 1.11 m and its mass is m = 26.8 g, what is the minimum period? (b) If d is chosen to minimize the period and then L is increased, does the period increase, decrease, or remain the same? (c) If, instead, m is increased without L increasing, does the period increase, decrease, or remain the same?

After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 50.0 cm. She finds that the pendulum makes 100 complete swings in 136 s. What is the value of g on this planet? (10.7 m/s³)

Mass and Spring: A 3.4 kg mass hangs in equilibrium from a spring. When the mass is displaced by 0.08 m and released from rest, it reaches a top speed of 2.5 m/s as it oscillates. A group of students records the motion of = 4520. the spring for 242 seconds and deduces the system has a quality factor of Q (a) What is the period of oscillation? (b) What is the spring constant of the spring?
