A cylindrical pellet, 1 mm in diameter and 3 mm in length, is dropped from a plane cruising at an altitude of 3 km. The density of this pellet is 7930 kg/m³. Calculate the terminal velocity of this pellet and the time (in hours) it will take for the pellet to reach the ground. Assume that the properties of air are constant (density = 1.246 kg/m³, viscosity is 1.778 x 105 Pa s) and that it follows Newton's Law. Round your answers to three significant figures.
