Q. The minimum distance required to stop a car moving at 34.0 mi/h is 38.0 ft. What is the minimum stopping distance for the same car moving at 65.0 mi/h, assuming the same rate of acceleration?

Q. A pair of speakers separated by 0.820 m are driven by the same oscillator at a frequency of 652 Hz. An observer originally positioned at one of the speakers begins to walk along a line perpendicular to the line joining the speakers. (Assume the speed of sound is 345 m/s.)How far must the observer walk before reaching a relative maximum in intensity?
