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
if you convert these into miles per hour 50 m/s would be higher, since
50 m/s = 111.85 mph and
140 km/h = 86.99 mph
When the ruler is broughı near the inetal knob, it repels electrons in the metal. Electrons move away froni the ruler and down the metal rod. The knob now has a positive charge. The thin pieces of metal foil at the bottom of the metal rod now have a negative charge.
Average speed = (total distance covered) / (time to cover the distance)
Total distance = (77km + 66km) = 143 kilometers
Time to cover the distance = 2 hours
Average speed = (143 km) / (2 hours) = 71.5 km per hour
