A careful student designed a rotational motion experiment where friction in the system was negligible so that / = 0 in the equations you used previously. A group of students then decided to mount the solid sphere to the top oh 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 incar acceleration of the falling mass was measured to be 26.58 mm/s (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/mojusing only symbolic algebra. (c) What s the numerical value for /m. (d) What is the numerical value of the tangential acceleration of point on the rim of the horizontal disk? ccall that: g = 9.80m/s Ihorizontal disk = - MR. Ithin spherical shell MR. olid sphere MR and Icylindrical shell = MR. R are same
