Homework Statement
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, Fd = kV, where V is the particle speed. Determine the time required for the particle to accelerate from rest to 95% of its terminal velocity, Vt, in terms of k, W, and g.
