Question

A centrifuge in a biochemistry laboratory rotates at an angular speed of 3,650 rev/min, clockwise (when viewed from above). When switched off,
it rotates through 48.0 revolutions before coming to rest. Assuming it is constant, what is the magnitude of angular acceleration (in rad/s²)?
rad/s²
What is the direction of the angular acceleration (again, when viewed from above)?
clockwise
оо
counterclockwise
The magnitude is zero.
