Question

The angular position of a point on the rim of a rotating wheel is given by θ = 4t – 3t² + t³, where θ is in radians if t is given in seconds.
a. What are the angular velocities for the time interval that begins at t = 2 and ends at t = 4s?
b.What is the average angular acceleration for the interval (t=2, t=4)?
c. What is the equation for angular acceleration?

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 .
