4. A uniform solid disk (I=1/2 mr') is released from rest and rolls without slipping down an inclined plane that makes an angle of 250 with the horizontal. What is the forward speed of the disk after it has rolled 3.0 m, measured along the plane? A) 2.0 m/s B) 3.5 m/s C) 4.1 m/s D) 5.7...

1) The parallel axis theorem provides a useful way to calculate the moment of inertia I about an arbitrary axis. The theorem states that I = Icm + Mh2, where Icm is the moment of inertia of the object relative to an axis that passes through the center of mass and is parallel to the axis of interest, M is the total mass of the object, and h is the perpendicular distance between the two axes. Use this theorem and...
