Say we got a fierce wheel, right? and at the top of that fierce wheel, we have the normal force, then we have this intrepidual acceleration going towards the center, then we have gravity going towards the center, right? and let's say we have another situation where you're at the bottom, right? so then the normal force is going up, and then this intrepital acceleration is going towards the center.
00:31
Gravity is still going down, right? so this is the top, right? so for the top, we can say that f -net, y is actually n minus m -g equals negative m -ac -c, by n -m -g equals negative m b squared over r, by n equals m -g, minus m v squared over r, or just m times g minus v squared over r.

Okay, and n is the apparent way, okay? now, it's also worth saying that b is 2 pi r over the period t.
01:29
So then that means that n is actually m times g minus 1 over r, times 2 pi r over t squared okay so then that is 62 times 9 .8 minus 1 over 12 .7 times 2 pi 12 .7 over 22 square yard okay and that is approximately 543 newtons 543 newtons okay and that's for the top now for the bottom we've got f net y n minus m g equals mac so then that is n equals mg plus macc or g sorry, m times g plus v squared over r...
