Angular Speed

  1. Jun 19, 2005 #1
    A solid sphere of radius 13.0 cm and mass 12.0 kg starts from rest and rolls without slipping a distance of L = 7.0 m down a house roof that is inclined at 32o. What is the angular speed about its center as it leaves the house roof? Use units of "rad/s".

    the Forum helps u, if u show us that u have worked upon anyway
    solve torque equation
    [tex]\Sigma \tau_{cm} =I \alpha[/tex]
    [tex]\Sigma F= Ma[/tex]
    Use condition of rolling
    [tex] a_{cm}=\alpha R[/tex]
