rcus of Physics raffic shock wave. An abrupt slowdown in concentrated traffic can travel as a pulse, termed a shock wave, along the line of cars, either ownstream (in the traffic direction) or upstream, or it can be stationary. The figure shows a uniformly spaced line of cars moving at peed v = 27.0 m/s toward a uniformly spaced line of slow cars moving at speed vs = 5.30 m/s. Assume that each faster car adds length L 13.0 m (car length plus buffer zone) to the line of slow cars when it joins the line, and assume it slows abruptly at the last instant. (a) or what separation distance d between the faster cars does the shock wave remain stationary? If the separation is twice that amount, hat are the (b) speed and (c) direction (upstream or downstream) of the shock wave?
