Homework Help: A Solid Sphere Release From Rest at the top of a Ramp.

  1. Nov 13, 2006 #1
    Please help me with this question. Thank you.

    A 2.0 kg solid sphere (radius = 0.10m) is released from rest at the top of a ramp and allow to roll without slipping. The ramp is 0.75m high and 5.3 m long. Find Ktotal, Krot, and Ktranslation.

    Pure rolling takes place, work done by friction is 0. Energy is conserved. Ktotal=mgh, Krot/Ktranslation=2/5 ie in ratio of moment of inertia. Ktranslation=5/7 mgh etc
