Rolling Motion question from NEET 1994 (AIPMT)

Q91NEET 1994 · AIPMTEasy

Rolling Motion

A solid spherical ball rolls on a table. Ratio of its rotational kinetic energy to total kinetic energy is

Show answer and solution

Answer: (d)

Solid sphere: $K_r = \frac{1}{5}mv^2$ , $K_{total} = \frac{7}{10}mv^2$ .
$\frac{K_r}{K_{total}} = \frac{1/5}{7/10} = \frac{2}{7}$
So the answer is (d) $\frac{2}{7}$ .
