2. A disk of radius 10.0 cm spins about an axis through its center at a constant 5.0 rad/s. What is the linear velocity, centripetal and tangential accelerations of a point on its rim? linear velocity = centripetal acceleration = tangential acceleration = 3. Under what conditions is the linear momentum of a system conserved? (Do not state when the initial is equal to the final.)
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass.
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass. The axis is perpendicular to the disk. The moment of inertial for the disk with a central axis is I MR2. Two non-rotating smaller disks, each with mass M2 and radius R/4, are glued on the original disk as shown in the figure. (a) Show that the ratio of the moments of inertia is given by I'/I = 35/16, where I' is the moment...
