A solid ball of density `rho_(1)` and radius r falls vertically through a liquid of density `rho_(2)`. Assume that the viscous force acting on the ball is `F = krv`, where `k` is a constant and v its velocity. What is the terminal velocity of the ball ?

A solid rubber ball orf density d and radius R falls vertically through air. Assume that the air resistance acting on the ball is F=KRV where K is constant and V is its velocity. Because of this air resistance the ball attains a constant velocity called terminal velocity v_(T) after some time. Then V_(T)

A spherical solid ball of volume V is made of a material of density rho_1 . It is falling through a liquid of density rho_2(rho_2ltrho_1) . Assume that the liquid applies a viscous force on the ball that is proportional to the square of its speed v, i.e., F_(viscous)=-kv^2(kgt0) . The terminal speed of the ball is
