A small bolt with a mass of 33.0 g sits on top of a piston. The piston is undergoing simple harmonic motion in the vertical direction with a frequency of 3.05 Hz. What is the maximum amplitude with which the piston can oscillate without the bolt losing contact with the piston's surface? Use g = 9.81 m/s^2 for the acceleration due to gravity.

    A=0.0267 m

    Explanation:

    Given that

    m = 33 g = 0.033 kg

    Frequency, f = 3.05 Hz

    We know that

    ω = 2 π f

    ω = 2 x 3.05 π

    ω = 6.1 π s⁻¹

    ω² m = K

    K=Spring constant

    (19.16) ² x 0.033 = K

    K = 12.11 N/m

    The maximum amplitude A

    K A = m g

    12.11 x A = 0.033 x 9.81

    A=0.0267 m
