A small, spherical bead of mass 2.90 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 = 1.76 cm/s.\ (a) Find the value of the constant b in the equation = ?b. (b) Find the time t at which the bead reaches 0.632vT. (c) Find the value of the resistive force when the bead reaches terminal speed.
