A cyclindrical object of mass M and radius R rolls smoothly fromrest down a ramp

Question

A cyclindrical object of mass M and radius R rolls smoothly fromrest down a ramp and onto a horizontal section. From there it rollsoff the ramp and onto the floor, landing a horizontal distanced=.506 m from the end of the ramp. The initial height ofthe object is H= .90m; the end of the ramp is at h=.10 m. The object consists of an outer cylindrical shell (of acertain uniform density) that is glued to a central cylinder (of adifferent uniform density). The rotational intertia of the objectcan be expressed in the general form I=MR2 (R is squared), but isnot .5 as it is for a cylinder of uniform density. Determine.

Explanation / Answer

Is there a picture for this? Specifically, is the 0.90m heightrelative to the ground of which it falls at the end of the ramp? Oris 0.90m relative to the 0.10m the ramp is raised ? Or...
