Question

A sphere of mass m rolls without slipping on an inclined plane of inclination θ. The linear acceleration of the sphere is:

• A. $\frac{1}{7}$g sin θ
• B. $\frac{2}{7}$ g sin θ
• C. $\frac{3}{7}$ g sin θ
• D. $\frac{5}{7}$ g sin θ

Answer 1

Answer: (D)

$\frac{5}{7}$ g sin θ

Answer 2

a = $\frac{g\sin\theta}{1 + \frac{I}{mR^{2}}}$
