a.
The polar equation that models the possible positions of a passenger car.
a.
Answer to Problem 109E
Explanation of Solution
Given information:
The centre of a Ferris wheel lies at the pole of the polar
Calculation:
From the given information, passengers enter a car at
Since the passenger enters the car at
Which represents a circle with radius
Thus, the polar equationthat models the possible positions of a passenger car is
b.
The interpretation and coordinates after some seconds of rotations.
b.
Answer to Problem 109E
Explanation of Solution
Given information:
The centre of a Ferris wheel lies at the pole of the polar coordinate system, where the distances are in feet. Passengers enter a car at
Calculation:
Starting from the bottom
The coordinates will be:
Thus, the coordinates are
c.
The conversion the point in part (b) to rectangular coordinates.
c.
Answer to Problem 109E
Explanation of Solution
Given information:
Calculation:
From (b), the polar coordinate is
Find the
Find the
The rectangular coordinate is
This means that the car is
