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?
