A small, spherical bead of mass m = 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 v = cm/s. Find
(a) the value of the constant b that appears in Equation 6.2,
(b) the time t at which the bead reaches 0.632vT, and
(c) the value of the resistive force when the bead reaches terminal speed.
