Question:
Very small particles moving in fluids are known to experience a drag force proportional to speed. Consider a particle of net weight \(W\) dropped in a fluid. The particle experiences a drag force, \(F_{D}=k V\), where \(V\) is the particle speed. Determine the time required for the particle to accelerate from rest to 95 percent of its terminal speed, \(V_{t}\), in terms of \(k, W\), and \(g\).
