A spring having a spring constant 1200 N is mounted on a horizontal table as shown in figure. A mass of 3 kg unattached to the free end of the spring. The mass is then pulled sideways to a distance of 2.0 cm and released. Determine (i) the frequency of oscillations, (ii) maximum acceleration of the mass, and (iii) the maximum speed of the mass.
