Calculate the terminal velocity in free fall of a bowling ball (mass of 7.2 kg, diameter of 21.6 cm) and a basketball (mass of 0.51 kg, diameter of 23.85 cm). The bowling ball can be considered a smooth sphere (Cd = 0.1), while the basketball can be considered a rough sphere (Cd = 0.4). What would be the terminal velocity of the basketball if we considered it a smooth sphere?
