Block sliding Down; find kinetic coefficient

  • #26
I'm sorry.

I'm honestly stuck on this problem. I think I summed the forces right (since I could solve for us and get the right answer).

But, when it gets to finding the acceleration, I'm confused.

Maybe if I think about it some more.....

No matter how many times I do this problem, I still get .305 as uk.....

So, I don't know. Maybe there was a rounding thing that was done somewhere to make it different than .305.

Well thank you.



If anyone else has any help, please, I'd really appreciate it.
