Vedclass · Answer

(A) The acceleration of a body rolling down an inclined plane is given by $a = \frac{g \sin 	heta}{1 + \frac{I}{mR^2}}$.The moment of inertia $I$ for the objects are: $I_{	ext{ring}} = mR^2$,$I_{	ext{cylinder}} = \frac{1}{2}mR^2$,and $I_{	ext{sphere}} = \frac{2}{5}mR^2$.Comparing the moments of inertia: $I_{	ext{ring}} > I_{	ext{cylinder}} > I_{	ext{sphere}}$.Since $a$ is inversely proportional to the factor $(1 + \frac{I}{mR^2})$,the acceleration follows the order: $a_{	ext{ring}} Using the kinematic equation $v^2 = u^2 + 2as$ with $u = 0$,the final velocity $v = \sqrt{2as}$ is directly proportional to the square root of acceleration.Therefore,the final velocities at the bottom of the plane follow the order: $v_{	ext{ring}} Thus,the sphere has the greatest velocity and the ring has the least velocity.

Consider a situation in which a ring,a solid cylinder,and a solid sphere roll down on the same inclined plane without slipping. Assume that they start rolling from rest and have identical diameters. The correct statement for this situation is:
