Question

<p><strong>A 2 kg mass and a 5 kg mass are attached toeither end of a 3 m long massless rod.</strong><br/><br /><strong>a.) Find the center of mass of thesystem.</strong><br /><strong>1Your answer iscorrect. m, from the 2 kg mass. <span style="color:#ff0000;">I Answered: 2.143 (ItsCorrect)</span></strong><br /><br/><strong>b)Find the rotational inertia (I) of the systemwhen rotated about: </strong>2<strong>kgm2</strong><br /><strong></strong><br/><strong>c.) the end with the 5 kgmass.</strong><br /><strong>&#160;kgm2</strong><br/><strong></strong></p>
<p><strong>d.) the center of therod.</strong><br /><strong>&#160;kgm2</strong><br/><strong></strong></p>
<p><strong>e.) the center of mass of thesystem.</strong><br /><strong>&#160;kgm2</strong><br /><strong>(Compare this to partsb-d. Is this what you expect?)</strong><br /><br/><strong>f.) If the system is rotated about the center ofmass by a force of 10 N acting on the 5 kg mass, (perpendicular tothe rod), what will the size of the angular acceleration of thesystem be?</strong><br/><strong>&#160;rad/s2</strong></p>
