1) Explain why an object too far from the motion detector will produce an incorrect distance reading?

2) Look up an approximate value for the speed in air for 49 kHz ultrasound.Record your value in m/s and give the source of your information.

3) Estimate the dead time of the ultrasonic detector after emitting a pulse.

4) Explain why only consider one-dimensional motion when using a single motion detector. Based on the definition of velocity, describe what you should observe in the velocity vs. time graph if you were measuring a stationary, distant object and you suddenly slid an object into the beam from slide.
