<p>I need help on rotation dynamics.</p>
<p>If I have a cylinder, sphere, and a hoop, which has the greatest kinetic energy?</p>
<p>Which object has the greatest translational kinetic energy?</p>
<p>Which object requires the required the greatest coefficient of static friction to prevent it from slipping?</p>
<p>Which object has the greatest rotational acceleration?</p>
