Question

A pulley of mass 0.208 kilograms and radius 4.31 centimeters experiences an unbalanced torque of 0.00244 newton·meters.

a. What is the pulley's angular acceleration? Include units in your answer. More information.

b. If it started from rest, how much would the pulley have rotated after 2.35 seconds? Include units in your answer. More information.

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 .
