A pancake-shaped solid wood disk (m = 1.4 kg) is placed at the top of an inclined plane. It begins to roll down the plane on its own.
A) Which is larger during this rolling, the work done by friction to increase the rotational speed or the work done by friction to keep the object from linearly moving down the plane?
B) What is the linear acceleration of the disk referred to if the angle of the hill is 30°?
C) How long will it take for the disk to roll 5.0 m along the plane?

A thin light string is wrapped around a solid uniform disk of mass M and radius R, mounted as shown. The loose end of the string is attached to the axle of a solid uniform disc of mass m and the same radius r which is can roll down without slipping down an inclined plane that makes angle θ with the horizontal. Find the acceleration a of the rolling disc. Neglect friction in the axle of the pulley. a =...
