A solid sphere of mass

1.2\,\text{kg}

and radius

0.10\,\text{m}

is released from rest on a

15^\circ

incline. Neglect air resistance. What is the magnitude of the sphere’s linear acceleration as it begins to roll without slipping? (a)

2.5\,\text{m/s}^2

(b)

1.5\,\text{m/s}^2

(c)

1.8\,\text{m/s}^2

(d)

3.7\,\text{m/s}^2
