SUMMARY
The coefficient of static friction between two oscillating blocks can be determined using the relationship between the maximum acceleration and the gravitational force acting on the upper block. Given that the blocks oscillate with a period of 1.5 seconds and the upper block begins to slip at an amplitude of 36 cm, the maximum acceleration can be calculated using the formula a = (ω²) * A, where ω is the angular frequency. The angular frequency can be derived from the period, leading to a precise calculation of the coefficient of static friction (µ).
