Question

Consider a merry-go-round with mass 30.00kg and radius 1.40m (the merry-go-round can be modeled as a solid cylinder). A girl exerts a tangential force of 140.00N on the very edge of the merry-go-round. Determine the angular acceleration of the merry-go-round as this force is applied. rad/s^2

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 .
