Problem. A small sphere of mass 2.00 g is released from rest in a large vessel filled with oil. It experiences a resistive force proportional to its speed. The sphere reaches a terminal speed of 5.00 cm/s. Determine the time constant ? . Ignore the buoyant force. Answer: ? = 5 · 10−3 s. with detailed explanation and calculation
Terminal speed is the constant speed acheived by a body accelerating in a resistive medium.
