Chapter 1, Problem 4P

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 percent of its terminal speed, Vt, in terms of k, W, and g.

Very small particles moving in a fluid are known to experience a forcedrag proportional to speed. Consider a particle with a net weightW is dropped into a fluid. Particles experience drag, FD = kV,where V is the velocity of the particle. Determine the time required for the particle toaccelerates from rest to 95 percent of its terminal speed(stopping) Vt, in terms of k, W, and g.
A block of mass m slides along a horizontal surface lubricated with a thick oil which providesa drag force proportional to the square root of velocity.F_d=-bv^1/2If v = v0 at t = 0, determine v as a function of time
