    Question

    A mass of 0.1 kg executes SHM with amplitude 10 cm. Its

    kinetic energy at the mean position is 8 Γ— 10-3 J. What is its equation of motion if the initial phase is 45Β°?
    A x = 0.1 sin(4t + Ο€/4) Correct Answer Incorrect Answer
    B x = 0.1 cos(8t + Ο€/4) Correct Answer Incorrect Answer
    C x = 0.1 cos(4t – Ο€/4) Correct Answer Incorrect Answer
    D x = 0.1 sin(4t – Ο€/4) Correct Answer Incorrect Answer

    Solution

    The mass m=0.1kg. The amplitude A=10cm=0.1m. The kinetic energy at the mean position is the total energy of the SHM:
