In Fig. 3, an annular copper cylinder of radii Router = 40 cm, Rinner = 20 cm and mass M = 5 kg rolls from rest a D = 10 m distance down a Ф = 30° incline. Assume that the incline and the horizontal surface have the same fictional coefficient. a/ Compute the speed of the center of mass of the cylinder at the end of
the incline.
b/ How long does the cylinder reach to the bottom of the incline?
c/ If the annular copper cylinder and a solid wood cylinder having the same radius Router and mass release

together from rest at the initial location, which cylinder reaches the bottom first? Why?
