A small sphere of mass 9.50 g is released from rest in a large vessel filled with oil, where it experiences a resistive force proportional to its speed. The sphere reaches a terminal speed of 9.00 cm/s. Determine the time constant, and the time at which the sphere reaches 85.0% of its terminal speed.
