A 9.00 kg object starting from rest falls through a viscous medium and experiences a resistive force = -b , where is the velocity of the object. The object reaches one half its terminal speed in 5.54 s.

(a) Determine the terminal speed.
(b) At what time is the speed of the object three-fourths the terminal speed?
(c) How far has the object traveled in the first 5.54 s of motion?
