I stumbled across your blog this morning; it looks like a great 
resource. I’m teaching Physics C (mechanics only) for the first 
time and I’m always looking for more information. Good stuff, 
kep it up!

Very helpful thanks—now I understand the equations better.

A blog on physics! I haven’t seen that before! I never liked 
physics like I should have while I was in college. I don’t know 
why. Just dropping by! Keep up the good work! I bet there
 are many people especially physics students finding your site
 very useful!

All right I understood the formula of calculating the acceleration
 of a rolling body. Is there a formula for calculating the velocity 
of a rolling body down the inclined plane?

Hello roshanboy,
To obtain the linear velocity down the plane, just substitute 
the value of the acceleration in the equation of linear motion
 such as v = u + at or v^2 = u^2 + 2as. You can use the 
energy relation, mgh = (1/2) mv^2 +(1/2)Iω2 also to find the
 velocity. Here ‘h’ is the height of the inclined plane, ‘I’ is the 
moment of inertia and ‘ω’ is the angular velocity which is v/R 
where R is the radius of the rolling body. Don’t think of a 
ready made formula for ‘v’.
