Frictional Force on Drum Rolling Down an Inclined Plane (2005)

A drum of radius R and mass M, rolls down without slipping along an inclined plane of angle $theta$. The frictional force: (2005)

Converts translational energy to rotational energy
Dissipates energy as heat
Decreases the rotational motion
Decreases the rotational and translational motion

Solution:

Static friction provides the necessary torque for rolling without slipping, converting translational kinetic energy into rotational kinetic energy without dissipating mechanical energy.
