Homework Statement
I do not understand how a was solved for. the picture is a sphere rolling down a hill. Asked to solve for a.
Homework Equations
solve for a, use alpha = a/r
ma = mg sin theta - fs; T = fs*r = I*alpha = (2/5)mr^2; fs = (2/5)ma
a = (5/7)g sin theta
I can't see the progression through these steps
