An iceberg breaks off from the Antarctic continent and floats due north at constant velocity/ It's latitude south decreases by 1 degree in 8 days. Taking the circumference of the earth to be 40 000km, calculate the speed of iceberg in ms^-1.

  • math -

    Hint:
    Circumference=40000km
    radius, r
    = 40000/(2π) km
    = 40000/(2π)*1000 m

    angular speed, ω
    = 1 degree/8 days
    = (π/180)rad. / (8*86400) sec.

    terrestrial speed
    = rω


    I get less than a metre per second.
