Problem

Damping ** A particle with mass mm and initial speed VV is subject to a velocity-dependent damping force of the form bvnbv^n. (a) For n=0,1,2,…n = 0, 1, 2, \ldots, determine how the stopping time depends on mm, VV, and bb. (b) For n=0,1,2,…n = 0, 1, 2, \ldots, determine how the stopping distance depends on mm, VV, and bb. Be careful! See if your answers make sense. Dimensional analysis gives the answer only up to a numerical factor. This is a tricky problem, so don't let it discourage you from using dimensional analysis. Most applications of dimensional analysis are quite straightforward.
