A drum of radius $R$ and mass $M$ rolls down without slipping along an inclined plane of angle $\theta$. The frictional force:
  1. dissipates energy as heat
  2. decreases the rotational motion'
  3. decreases the rotational and translational motion
  4. converts translational energy to rotational energy

Solution

Required frictional force converts translational energy into rotational energy. ~
