' A careful student designed a rotational motion experiment where friction in the system was negligible so that f=0 in the equation you used previously. a group of students then decided to mount the sclid sphere to the top of the horizontal disk. the solid sphere and disk have the same mass, M, and radius, R. the radius of the pulley, r, was exactly 1/18 of the radius of the disk and the linear acceleration of the falling mass was measured to be 26.58 mm/s"2. (A) Using only symbolic algebra, calculate the moment of inertia of the disk and solid sphere together. (B) Find the ratio of the mass of the disk to the mass of the falling mass, M/m, using only symbolic algebra (C) What is the numerical value for M/m? (D) What is the numerical value of the tangential acceleration of a point on the rim of the horizontal disk? Given : g=9.80 m/s"2......... inertia of horizontal disk=1/2 MR"2.............. inertia of thin spherical shell= 2/3MRM2............ inertia of solid sphere= 2/5MR"2.............inertia of cylindrical shell= MR"2
