Car A is moving with constant speed v on the straight and level highway. The police officer in the stationary car Pattempts to measure the speed v with radar. If the radar measures "line-of sight" velocity, what velocity v' will the officer observe? Evaluate your general expression for the values v = 78 mi/hr, L= 480 ft, and D = 17 ft, and draw any appropriate conclusions.
