A cube has a drag coefficient of 0.8. what would be the terminal velocity of a sugar cube 1 cm on a side in air (ρ = 1.2 kg/m3) ? take the density of sugar to be 1.6 x 103 kg/m3.

    To answer this question, we should know the formula for the terminal velocity. The formula is written below:

    v = √ (2mg/ρAC)

    where

    m is the mass

    g is 9.81 m/s²

    ρ is density

    A is area

    C is the drag coefficient

    Let's determine the mass, m, to be density*volume.

    Volume = s³ = (1 cm*1 m/100 cm) ³ = 10⁻⁶ m³

    m = (1.6*10³ kg/m³) (10⁻⁶ m³) = 1.6*10⁻³ kg

    A = (1 cm * 1 m/100 cm) ² = 10⁻⁴ m²

    v = √ (2*1.6*10⁻³ kg*9.81 m/s²/1.6*10³ kg/m³*10⁻⁴ m²*0.8)

    v = 0.495 m/s
