Two highways intersect as shown in Fig. 4-46. At the instant shown, a police car P is distance dP = 760 m from the intersection and moving at speed vP = 76 km/h. Motorist M is distance dM = 480 m from the intersection and moving at speed vM = 48 km/h. What are the (a)x-component and (b)y-component of the velocity (both in km/h) of the motorist with respect to the police car? (c) For the instant shown in Fig. 4-46, what is the angle between the velocity found in (a) and (b) and the line of sight between the two cars?
