intro to physics problem..help plz final tomorrow?
A 3.15 kg solid cylinder ROLLS from rest down an incline of height 1.65 m. Find it's speed at the bottom......
there is a picture of a little ball rolling off a triangle like hill with a height of 1.65 m.
any help will be greatly appreciated...
Update:i also get around 5.6 as the answer, however my professor puts the answer on the review guides and the answer to this problem is 4.64 m/s^2

There is no solution because there is an elephant in the way.
i'm no longer so particular with regard to the rolling section... even even though it is an basic potential project. you comprehend potential preliminary = potential very final. So mgh = a million/2mv ^ 2. if so this is only plug and chug.
use this formula:
mgh = 1/2mv^2
