A ball of density 3500 kg m−3 and radius 6.0 mm is released from rest in a liquid of density 920 kg m−3 and viscosity 0.70 Pa s .
a. What is the terminal speed of the ball as it falls through the liquid? Ignore the buoyant force.
b. How do you expect the answer to a to change if the liquid temperature is increased?
c. Repeat a taking the buoyant force into account.
