    The velocity of a simple harmonic oscillator is given by:

    v = -9.55sin(21.8t) (mks units)

    a.) What is its angular frequency?

    b.) What is the amplitude of the motion in meters to two decimal places?

    c.) To the nearest hundredth of a meter where is the mass at the time t=18.29 seconds?

    d.) If the mass in letter c is 0.74 kg, what is the spring's potential energy to the nearest tenth of a joule?

    e.) What is its kinetic energy to the nearest tenth of a joule?
