A metallic spherical particle of density 7001 kg m⁻³ and diameter 1 mm is settling steadily due to gravity in a stagnant gas of density 1 kg m⁻³ and viscosity 10⁻⁵ kg m⁻¹ s⁻¹. Take g = 9.8 m s⁻². Assume that the settling occurs in the regime where the drag coefficient C_D is independent of the Reynolds number, and equals 0.44. The terminal settling velocity of the particle, in m s⁻¹, rounded off to 2 decimal places, is ______
