I would never be able to type the math here. So print this example out, and work thru it. It is welldone.

A small sphere of mass
m = 0.520 kg
is dropped from rest into a viscous liquid in which the resistive force on the sphere can be expressed as
FD = −bv,
and reaches one-fourth of its terminal speed in
3.14 s.
(a) What is the terminal speed of the sphere?
m/s
(b) What is the distance traveled by the sphere in
3.14 s?
