Calculate the moment of inertia of a skater given the following information. (a) The 60.0-kg skater is approximated as a cylinder that has a 0.110-m radius. (b) The skater with arms extended is approximately a cylinder that is 52.5 kg, has a 0.110-m radius, and has two 0.900-m-long arms which are 3.75 kg each and extend straight out from the cylinder like rods rotated about their ends.

Step 1</p>

We have to find the moment of inertia of a skate. Given mass of the skate is m=60 kg and radius of the cylinder is r=0.110m.

Step 2</p>

A)

Where I=moment of inertia, m=mass and r=radius.

0.363kgm2 is the moment of inertia of a skate.
