Physics is a cumulative subject, so make it sure you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter! ________________________________________________________________________________ A. Relative Motion Two highways intersect as shown in the figure below. At the instant shown, a police car P is distance d P = 800 m from the intersection and moving at v P = 30 m/s. Motorist M is distance d M = 600 m from the intersection and moving at speed v M = 20 m/s. What is the minimum separation between the two cars? B. Newton’s Laws Two horizontal forces F 1 and F 2 act on a 5.0 kg disk that slides over frictionless ice, on which an xy coordinate system is laid out. Force F 1 is in the positive direction of the x axis and has a magnitude of 8.0 N. Force F 2
