Question

Angular acceleration of disk is defined by the relation

Answer 1

$\mathfrak{The\:Answer\:is}$


The magnitude, or length, of theangular acceleration vector is directly proportional to the rate of change ofangular velocity, and is measured in radian s per second squared (rad/s 2or rad. s -2 ). Alternatively, the angular acceleration magnitude can be expressed in degrees per second squared (deg/s 2 or deg. s -2 )
