(a) The angular acceleration is given by:
where
is the final angular velocity
is the initial angular velocity
is the time interval
Let's convert the angular velocities in rad/s and the time in seconds:
Substituting the numbers into the equation, we find the angular acceleration:
(b) The tangential acceleration is given by the product between the angular acceleration and the distance of the point from the axis of rotation. In this case, the distance is
Therefore the tangential acceleration is
(c) The radial acceleration (also known as centripetal acceleration) is given by the product between the square of the angular velocity and the distance from the axis of rotation:
