Question

what is the angular displacement if it moves 1 and half round of circle​

Answer 1

Explanation:

Angular displacement of a body is the angle in radians (degrees, revolutions) through which a point revolves around a centre or line has been rotated in a specified sense about a specified axis.

When a rigid body is rotating about its own axis, the motion ceases to become a particle. It is so because in a circular path velocity and acceleration can change at any time. ... The angle made by the body from its point of rest at any point in the rotational motion is the angular displacement.
