Question:

A small, spherical bead of mass 3.00 g is released from rest at t = 0 in a bottle of liquid shampoo. The terminal speed is observed to be vT = 2.00 cm/s. Find (a) The value of the constant b in Equation 6.2, (b) The time, at which the bead reaches 0.632vT, and (c) The value of the resistive force when the bead reaches terminal speed.
