1. The largest and the smallest balls used in the experiment are with diameter 9.52 mm, and 2.38 mm respectively. For a glycerin with viscosity 1.5 Pa.s, what is the time necessary for each ball to rich a velocity 99% of the terminal velocity? Density of the ball material is given in the text. Round the result to three decimal places.
2. What is the Reynolds number for the fastest falling ball in the experiment. Use the same data as in problem 1, glycerin density of 1.30 g/cm^3, and acceleration of gravity 9.81 m/s^2.
