A disk rotates at constant angular acceleration, from
Chapter , Problem 80(choose chapter or problem)
A disk rotates at constant angular acceleration, from angular position u1 ! 10.0 rad to angular position u2 ! 70.0 rad in 6.00 s. Its angular velocity at u2 is 15.0 rad/s. (a) What was its angular velocity at u1? (b) What is the angular acceleration? (c) At what angular position was the disk initially at rest? (d) Graph u versus time t and angular speed v versus t for the disk, from the beginning of the motion (let t ! 0 then).
