You drop a steel ball bearing, with a radius of 3.40 mm, into a
beaker of honey. Note that honey has a viscosity of 6.00 Pa/s and a
density of 1360 kg/m3, and steel has a density of 7800 kg/m3.
Assume that g = 9.8 m/s2. (a) What is the terminal speed of the
ball bearing? m/s (b) Aluminum has a density of 2700 kg/m3. What
radius should an aluminum ball have to have the same terminal speed
in honey...
