Medium MCQ +4 / -1

A solid cylinder rolls without slipping. The ratio of translational KE to the total KE is:

  1. A 1/3
  2. B 1/2
  3. C 2/3 Correct answer
  4. D 3/4

Solution

$I = \frac{1}{2}MR^2$. $KE_{trans} = \frac{1}{2}Mv^2$, $KE_{rot} = \frac{1}{4}Mv^2$. Ratio = $\frac{1/2}{3/4} = 2/3$.
