PhysicsEasy49×since 2002Q8065A round uniform body of radius R,R,R, mass MMM and moment of inertia III rolls down (without slipping) an inclined plane making an angle θ\thetaθ with the horizontal. Then its acceleration isAg sinθ1−MR2/I{{g\,\sin \theta } \over {1 - M{R^2}/I}}1−MR2/IgsinθBg sinθ1+I/MR2{{g\,\sin \theta } \over {1 + I/M{R^2}}}1+I/MR2gsinθCg sinθ1+MR2/I{{g\,\sin \theta } \over {1 + M{R^2}/I}}1+MR2/IgsinθDg sinθ1−I/MR2{{g\,\sin \theta } \over {1 - I/M{R^2}}}1−I/MR2gsinθCheck answerSkip
