To solve this problem we will apply the descriptive equations of the movement of a mass-spring system, which describe the angular velocity as a function of the spring constant and the mass, the kinetic energy as a function of its linear velocity and the potential energy as a function of the spring constant and spring compression.
Finally we will calculate the amplitude of the system through the relation of energy in the harmonic movement, let's start:
PART A) The angular velocity is described as
here,
k = Spring constant
m = Mass
We have all of this values then the angular velocity is
Therefore the frequency of the motion would be given by
PART B) Now the potential energy is given as function of the spring constant and the displacement squared, then
PART C) Kinetic energy is given as function of the mass and velocity squared, then
PART D) The total energy of the system is equivalent to half the product between the amplitude squared and the spring constant, said total energy per conservation must be equivalent to the sum of the kinetic and potential energy previously found, therefore,
Solving for A,
Therefore the amplitude of the motion is 0.85m
