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.)
