Question

A rope is wrapped around a circular pulley such that its acceleration is given by a = 10t (in m/s², where t is in seconds)
If it starts from rest, determine (a) angular acceleration, (b) angular velocity, and (c) angular displacement at t = 4 seconds.

Definition Definition Angle at which a point rotates around a specific axis or center in a given direction. Angular displacement is a vector quantity and has both magnitude and direction. The angle built by an object from its rest point to endpoint created by rotational motion is known as angular displacement. Angular displacement is denoted by θ, and the S.I. unit of angular displacement is radian or rad.
