Sorry but it doesn't really show me anything except for a picture of an object spinning horizontally with a mass at the end.

I was thinking about using the F=ma formula but I'm pretty much stuck.

It also shows a weight that presumably can pull the string through the tube making the radius of rotation shorter.

PS: Stopper?
 
This really has to be reposted with the template filled. I think that filling correctly the "Relevant equations" section of the template will be helpful.

Thread closed.
