Question

Al and Betty have gone to the amusement park to ride on a Ferris wheel. The wheel in the park has a radius of 15 feet, and its center is 20 feet above ground level. Assume it takes 24 seconds to make a complete revolution.

You can describe the various positions in the cycle of the Ferris wheel in terms of the face of a clock, as indicated in the accompanying diagram. Think of Al and Betty's location as they ride as simply a point on the circumference of the wheel's circular path. That is, ignore the size of the Ferris wheel seats, Al and Betty's own heights, and so on.

Answer 1

Answer:a) The 12 o'clock position: Al and Betty are 35 feet above the ground when they are at the 12 o'clock position on the Ferris wheel.

b) The 9 o'clock position: Al and Betty are 5 feet above the ground when they are at the 9 o'clock position on the Ferris wheel.

c) The 6 o'clock position: Al and Betty are 20 feet above the ground when they are at the 6 o'clock position on the Ferris wheel.

d) The 8 o'clock position: Al and Betty are 5 feet above the ground when they are at the 8 o'clock position on the Ferris wheel.

e) 10 seconds after passing the 11 o'clock position: Al and Betty are 35 feet above the ground when they are 10 seconds after passing the 11 o'clock position on the Ferris wheel.

2) Al and Betty are 30 feet above the ground when they are at the 2 o'clock position on the Ferris wheel.
