Problem

A solid cylinder of mass

4.0\,\text{kg}

and radius

0.20\,\text{m}

is released from rest at the top of a rough incline that makes an angle of

30^{\circ}

with the horizontal. Neglect air resistance. What is the magnitude of the cylinder’s linear acceleration down the incline? (a)

6.5\,\text{m}\!/\!\text{s}^{2}

(b)

2.4\,\text{m}\!/\!\text{s}^{2}

(c)

3.3\,\text{m}\!/\!\text{s}^{2}

(d)

4.9\,\text{m}\!/\!\text{s}^{2}
