Starting from rest, ahollow ball rolls down a ramp inclined at angle θ to the horizontal. Find an expression for its speed after it's gone a distance d along the incline.
I for sphere = 2/5*M*R^2
The Attempt at a Solution
I know we have to use v^2=u^2+2ax
and we have to find the angular acceleration however I am not sure how to relate both of them.
