The table of values shows the height of a car of a Ferris wheel as it travels in a circular motion.

Question

Which statements are true?

1. The radius of the Ferris wheel is 25 yd.
2. The maximum height of the Ferris wheel above ground is 50 yd.
3. The car makes a complete revolution in 12 s.
4. If the car is loaded at 0 s, then people are loaded at the lowest height of the Ferris wheel.

Table:

Time(seconds) [0, 3, 6, 9 12, 15, 18, 21, 24] Height(yards) [30, 55, 30, 5, 30, 55, 30, 5, 30]

Answer 1

1 is true as the distance from the highest point to the lowest point is 55 - 5 = 50 which is the diameter of the wheel.

3 is true as it takes 12 seconds for the height sequence to repeat itself.
