A coin rolls on a horizontal plane. What fraction of its total kinetic energy is rotational ?

Text Solution

AI Generated Solution

To solve the problem of finding the fraction of the total kinetic energy that is rotational for a coin rolling on a horizontal plane, we can follow these steps: ### Step 1: Understand the Kinetic Energy Components The total kinetic energy (KE_total) of a rolling object is the sum of its translational kinetic energy (KE_trans) and its rotational kinetic energy (KE_rot): \[ KE_{\text{total}} = KE_{\text{trans}} + KE_{\text{rot}} \] ...
