In the figure below, a solid cylinder of radius 12 cm and mass 8 kgstarts from rest and rolls without slipping a distance L = 6.0 mdown a roof that is inclined at angle ? = 30°.
(a) What is the angular speed of the cylinder about its center asit leaves the roof?
1 rad/s
(b) The roof's edge is at height H = 5.0 m. How far horizontallyfrom the roof's edge does the cylinder hit the level ground?
2 m
