A disk rotates at constant angular acceleration, from angularposition u1 10.0 rad to angular position u2 70.0 rad in 6.00 s. Itsangular velocity at u2 is 15.0 rad/s. (a) What was its angular velocityat u1? (b) What is the angular acceleration? (c) At what angular positionwas the disk initially at rest? (d) Graph u versus time t and angularspeed v versus t for the disk, from the beginning of the motion(let t 0 then).
