SUMMARY
The discussion focuses on calculating the frequency of a girl swinging from a rope with a mass of 40 kg and a length of 2.8 m. The correct approach involves using the formula for a simple pendulum, T = 2π√(L/g), where L is the length of the rope and g is the acceleration due to gravity (9.8 m/s²). The calculated period is 3.35 seconds, leading to a frequency of approximately 0.299 Hz. This method effectively demonstrates the relationship between period and frequency in pendulum motion.
