Science experiment huge Foucault pendulum oscilation explaining the rotation of the Earth

SOLVED: The Foucault pendulum experiment convicts in setting a long pendulum in motion at a point on the surface of the rotating Earth with its momentum originally in the vertical plane containing the pendulum bob and the point of suspension. Show that the pendulum's subsequent motion they be described by saying that the plane of oscillation rotates uniformly 2 πcos θradians per day, where θis the co-latitude. What is the direction of rotation? The approximation of small oscillations may be used

SOLVED:3) A pendulum that was originally erected by Foucault at the Pantheon in Paris for the Paris Exhibition in 1851 was restored in 1995.It has a 28.0 kg sphere suspended from 12.13 dm light cable If the amplitude of the swing is 324.00 cm, what is the maximum acceleration of the sphere?
