Homework Help: Translational Speed

  1. Jun 2, 2009 #1
    1. The problem statement, all variables and given/known data
    A solid cylinder with a mass of 1.12 kg and a radius of 0.017 m starts from rest at a height
    of 3.40 m and rolls down a 77.7◦ slope. What is the translational speed of the cylin-
    der when it leaves the incline? The acceleration of gravity is 9.81 m/s2 . Answer in units
    of m/s.
    2. Relevant equations
    I have angular speed which is

    we know r (.017m). But I'm having trouble finding the others.
    Any help would be great. Thanks.
