A block of mass m is being slid down along a frictionless wall by a known applied force A that makes an angle 0 with the vertical, as illustrated. If the block starts from rest and encounters a force of air resistance given by F, = kmv², how fast will the block be moving once it has been pushed a distance D down the wall?
