Mom! I want to go to the Ferris Wheel. I want to see the scenery of Canada at the highest point.
Ha-ha! I think so, too. But this Ferris wheel is moving at a uniform speed. It's so slow.
Is it dangerous to be so high? It should be very hot inside.
Don't worry, because the Ferris wheel has air conditioning in the room, so long as it doesn't open the window, it's safe. When the Ferris wheel reaches its highest point, it is 110 meters from the ground. It just take you guys 12 minute.
Do we have the same speed on the Ferris wheel? But why do you sometimes feel slow and sometimes fast?
Because when we choose the Ferris wheel as the reference target, we rotate at the same speed at each angle, but if we take the height as the reference target, the rising height of each time is different, so the speed will be different.
This is related to some mathematical problems. According to our programmer's calculation, we can know that the average change rate of Ferris wheel speed is 0.38m/s. It's 0.28m/s faster than the world's tallest London eye. So our Ferris wheel has good height and perfect time.
The reason why we sometimes feel fast and sometimes slow is that when we are rising, the horizontal distance from the initial point to the origin changes to 0.27m/s, which is slower than the average speed, so we feel slow when we are rising. And when it goes down, it's faster than the average, so it feels faster.
Ah! I see! Let's go to the queue quickly.
Well, let's go and see the beautiful scenery of Canada
