In an amusement park ride, a cylinder of radius 2.50 m is set in rotation at an angular speed of 4.10 rad/s. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider's clothing and the wall of the cylinder is needed to keep the rider from slipping?

I have found linear speed of 10.25 m/s but now I am stuck. Any help??

I was in Africa last year, and we came across this huge night-crawler. My daughter picked it up, and immediately it's whole body became fluorescent green. I threw it into a shopping bag and the bag glowed. Has anyone heard of this or seen it before? It was the largest and craziest worm I have ever seen.

I'm really into Earth & Space Science & have been reading alot of books for years now & the books have pictures of our Milky Way Galaxy in them.
How is Possible to take a picture of the Mily Way, when it would take like Millions of years just for the Space probe to reach a certain point to where it could snap an entire photo for it?
I think that they just make it up, & the Milky Way doesnt even look like that at all
