Question

An electric turntable 0.770 m in diameter is rotating about a fixed axis with an initial angular velocity of 0.230 rev/s. The angular acceleration is 0.895 rev/s^2.

In 0.191 s, the angular velocity is 0.401 m/s, 0.0603 rev, tangential speed at 0.970 m/s.

What is the magnitude of the resultant acceleration of a point on the tip of the blade at time ð‘¡ = 0.191 s. Express your answer in meters per second squared.

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 .
