(5/7) gsinΘ (the symbol is a theta)

give me the average acceleration of a solid sphere rolling down an incline, im not also sure where the 5/7 came from, ive herd of 2/5 for inertia but... AND is that linear acceleration or rotational.

that equation give about 0.6

i also get about 0.6 when i calculate the acceleration from my data by 2s/t^2 which is from s=ut+ 1/2 at^2

im also confused to why when i do v(final) - v (intial) / time

i do not get 0.6 well i do for the first value, then for the other distance i do not!!!!!

and ages ago i got 0.3 but now i cant even remember were that came from, i do get 0.3 if i do that eqaution for average v, but once again only for the first value.

thanks for any help, i think i just need reasuring that i am doing it right, as i have got .6 from to different things.
