A force can be a function of position, velocity, or time. Most of the forces we consider in an introduction to dynamics are constant forces, but the text does examine a drag force that is proportional to velocity for a falling object, resulting is a terminal velocity. For this challenge question, imagine a block of mass m sliding across a horizontal surface lubricated with a thick oil, and that the frictional force can be approximated as F, = -bvv If v = vo at time t=0, determine v and x as functions of time. Also show that the maximum distance the block could travel is 2mv3' „3/2 Xmax 3b
