The equation of motion for an oscillator is given by y= (0.200cm)sin (140t). What are the 1)alplitude, 2)period, and 3) frequency of this motion?

  • physics -

    y = (Amplitude)*sin(2 pi f t), therefore

    Amplitude = 0.200 cm
    Frequency (f) = 140/(2 pi) = 22.3 Hz

    Period P = 1/f = 0.0449 s
