Car A is moving with constant speed v on the straight and level highway. The police officer in the stationary car P attempts to measure the speed v with radar. If the radar measures "line-of sight" velocity, what velocity will the officer observe? Evaluate your general expression for the values v = 70 mi/hr. L = 500ft and D = 20 ft and draw any appropriate conclusions.
