Answer:
<em>The speed of the passengers is 5.24 m/s</em>
Explanation:
<u>Uniform Circular Motion </u>
It occurs when an object in a circular path travels equal angles in equal times.
The angular speed can be calculated in two different ways:
Where:
v = tangential speed
r = radius of the circle described by the rotating object
Also:
Where:
f = frequency
Since the frequency is calculated when the number of revolutions n and the time t are known:
The Ferris wheel has a diameter of 100 m and makes n=1 rotation in t=60 seconds, thus the frequency is:
The angular speed is:
Now we calculate the tangential speed, solving this formula for v:
The radius is half the diameter, r=100/2=50 m:
Calculating:
v = 5.24 m/s
The speed of the passengers is 5.24 m/s
