A buoy oscillates in simple harmonic motion according to the motion of waves at sea. An observer notes that the buoy moves a total of 6 feet from its lowest point to its highest point. The buoy returns to its highest point every 15 seconds.
Amplitude: 6 feet
Period: ???
Frequency: ???
Possible equation:???

  • physics - ,

    Period: 2pi/15, or one oscillation every 15 minutes.
    Freq: 1/15
    Equation: let d be the displacement then
    d = 6cos(2pi/15t)
