Homework Help: Maximum height

  1. Jun 19, 2005 #1
    thin hoop of radius r = 0.13 m and mass M = 8.1 kg rolls without slipping across a horizontal floor with a velocity v = 4.0 m/s. It then rolls up an incline with an angle of inclination theta = 33o. What is the maximum height h reached by the hoop before rolling back down the incline

    do it using conservation of energy...

    rotational K.E + linear K.E= P.E( at the hight reached on the inclined plane)
    take moment of inertia of a ring=1/2mr sqr abt the central axis while calculating rotational K.E.
    u will straightaway get the ans by cancelling out M
