In a television commercial, a small, spherical bead of mass 4.00 g is released from rest at t = 0 in a bottle of liquid shampoo. The terminal speed is observed to be 2.00 cm/s. Find (a) the value of the constant b in the equation v = mg/b (1 − e−bt/m), and (b) the value of the resistive force when the bead reaches terminal speed.
