What is the acceleration parallel to the surface of an inclined plane for a rolling body? Also,write the equation for the friction force acting parallel to the surface of the slope for a rolling body.

(N/A) For a body of mass $M$,radius $R$,and moment of inertia $I = kMR^2$ (where $k$ is a constant depending on the shape) rolling down an inclined plane with angle $\theta$:
$1$. The acceleration $a$ parallel to the slope is given by:
$a = \frac{g \sin \theta}{1 + k}$
$2$. The friction force $f$ acting parallel to the slope is given by:
$f = \frac{kMg \sin \theta}{1 + k}$
Here,$g$ is the acceleration due to gravity.
