Joe, standing near a straight road, records the sound of the
horn of a car traveling at a constant speed. The recorded frequency
as a function of the car's position along the road for trials at
different car speeds is accurately graphed below.
Greater than Less than Equal to When the car is far
away, the average of the frequencies moving in and out is ..... the
frequency at rest.
Greater than Less than Equal to The distance of Joe from
the path in R is ..... in T.
Greater than Less than Equal to The speed in trial T is
..... that in S.
Greater than Less than Equal to The speed in trial T is
..... to that in R.
Greater than Less than Equal to The speed in trial U is
..... that in other trials.
Greater than Less than Equal to The speed in trial Q is
..... that in other trials.
Using the data on the figure, calculate the speed of the car in trial Q. Use 340 m/s for the speed of sound.

A red car and a green car are traveling along a straight road in the same direction. The red car's position is given by x(t)=t3 and the green car is accelerating at a constant rate. At time t = 0, the green car is 132 m ahead of the red car. At t = 2 s, the red car reaches the same speed as the green car, and at t = 6 s, the red car catches up to the...
