A 10-cm diameter solid metal ball falls through the air at its terminal velocity of 39.3 m/s.

a) What would the new terminal velocity be if the mass of the ball were doubled, while the diameter and all other physical properties of the ball remained unchanged.

b) What would the new terminal velocity be if the diameter of the ball were doubled, while the mass and all other physical properties of the ball remained the same as the original?

c) What would the terminal velocity be for a ball of the same material (and thus same solid density) that has twice the diameter as the original?

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?
