Rolling cylinder on an incline

[andrewp7]

A cylinder of a mass M and a radius R starts at the top of a hill at a height h, and rolls to the bottom. At the bottom of the hill, what is its linear velocity, linear momentum, and angular momentum?


I believe the the velocity is sqrt((4/3)gh) and the the angular momentum is mvsin(theta) but I am not sure if those are right and I still d not know the linear momentum

You have to give all quantities in terms of M, R, and h. Theta is not given. Look after the definition of angular momentum, it is not mvsin(theta). The linear momentum is the same as the momentum of the CM of the cylinder.

wouldn't I need some type of angle because it is on an incline?

 

[ehild]

Do you? You got the speed without the angle, don't you? How did you got it? Using what law?
