A rough inclined plane is placed on a cart moving with a constant velocity $u$ on horizontal ground. A block of mass $M$ rests on the incline. Is any work done by force of friction between the block and incline? Is there then a dissipation of energy?

As the block $M$ is at rest.
Hence, $f=$ frictional force $=M g \sin \theta$
The force of friction on body is due to the tendency of block $M$ to slide down over the inclined plane.
Since, block is not in motion, so, no work is done by the force of friction. Hence, no dissipation of energy takes place.
