A small, spherical bead of mass 3.60 g is released from rest at t = 0 from a point under the surface of a viscous liquid. The terminal speed is observed to be vT = 1.64 cm/s.
(a) Find the value of the constant b in the equation = -b. (answer in N*s/m)
(b) Find the time t at which the bead reaches 0.632vT. (answer in s)
(c) Find the value of the resistive force when the bead reaches terminal speed. (answer in N)
