A spherical shell with a mass of 0.41 and a radius of 0.33 is to roll across the level ground under a constant angular acceleration of 2.5 rad/s². If is starts from rest, after what amount of time will its total kinetic energy be 67.4?

The moment of inertia for a spherical shell is I=2/3MR²

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
