Alright, thank you very much! I understand it a bit more now.

aha, i thought that since the distance from center is given as r in the assignment, i should give the answer as r aswell, since i can't really know if they are talking about meters or what..

So this means the highest possible radial acceleration must be 6.867 m/s^2. The radial acceleration --> A=v^2/r ---> 6.367=v^2/r To find velocity i find the circumference of one rotation and divide it by time. It takes 2 seconds to finish one rotation with a circumference of 2*pi*r, so...

How? The height is not given

I have found that the sum of forces must be facing inwards towards the circle, And I have come to the conclusion that the friction is the centripetal force in this instance. The friction force should be the only force working here. Therefore I am confused as to how i calculate when the cylinder...

This is attached to the assignment. English is my second language, so i might have misunderstood what you mean by diagram

I am not really sure how to go about this. I have been sick for a couple of weeks and fallen behind a bit. Can anyone help me out please? Thank you
