Answer 1

Question

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 .

An object rotates about a fixed axis, and the angular position of a reference line on the object is given by u = 0.40e2t, where u is in radians and t is in seconds. Consider a point on the object that is 4.0 cm from the axis of rotation. At t = 0, what are the magnitudes of the point’s (a) tangential component of acceleration and (b) radial component of acceleration?

A certain turntable of diameter 30 cm rotates horizontally about an axis through its center. At t = 0, a point on the edge of the turntable rotates from rest at a uniform tangential acceleration of 0.27 m/s2 , where t is in s, until the turntable reaches a final steady angular speed in 5 s. The turntable continues rotating at this final speed until it is switched off. (a) What is the angular displacement of the turntable, in revolutions, at t = 5 s, from rest? (b) What is the average angular velocity of the turntable at t = 9 s, from rest?
