A spherical solid ball of volume V is made of a material of density Ï1. It is falling through a liquid of
density Ï2 (Ï2 < Ï1). Assume that the liquid applies a viscous force on the ball that is proportional to the
nth power of its speed Ï
, i.e., Fviscous = – kÏ
n (k > 0). The terminal speed of the ball is
