Problem 16.5

A motion sensor can accurately measure the distance dto an object repeatedly via the sonar technique used inExample 16-2. A short ultrasonic pulse is emitted andreflects from any objects it encounters, creating echo pulsesupon their arrival back at the sensor. The sensor measuresthe time interval t between the emission of the original pulseand the arrival of the first echo, (a) The smallest time interval tthat can be measured with high precision is 1.0 ms. What is thesmallest distance (at 20C) that can be measured with themotion sensor? (b) If the motion sensor makes 15 distancemeasurements every second (that is, it emits 15 sound pulsesper second at evenly spaced time intervals), the measurementof t must be completed within the time interval between theemissions of successive pulses. What is the largest distance(at 20C) that can be measured with the motion sensor?(c) Assume that during a lab period the rooms temperatureincreases from 20C to 23C. What percent error will thisintroduce into the motion sensors distance measurements?
