A homogeneous sphere S, a uniform cylinder C, and a thin pipe P are in contact when they are released from rest on the incline shown. Knowing that all three objects roll without slipping, determine, after 6 s of motion, the clear distance between (a) the pipe and die cylinder, (b) the cylinder and the sphere. Give the answers in both U.S. customary and SI units.
