Two metal disks, one with radius R, = 2.50 cm and mass M, = 0.80 kg and
Question:
(a) What is the total moment of inertia of the two disks?
(b) Alight string is wrapped around the edge of the smaller disk, and a l.50-kg block is suspended from the free end of the string. If the block is released from rest at a distance of 2.00 m above the floor, what is its speed just before it strikes the floor?
(c) Repeat the calculation of part (b), this time with the string wrapped around the edge of the larger disk. In which case is the final speed of the block the greatest? Explain why this is so.
