A uniform drum of radius b and mass M rolls without slipping down a plane inclined at an angle \( \theta \) . The moment of inertia of the drum about its axis is \( I_0 = \frac{1}{2} M b^2\) . What is the linear acceleration ( a ) of the drum along the plane?
1
\( a = g \sin \theta\)
2
\( a = \frac{2}{3} g \sin \theta\)
3
\(a = \frac{3}{2} g \sin \theta\)
4
\(a = \frac{g \sin \theta}{2}\)
